The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows     local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a     double fetch vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states The security impact of this     bug is not as bad as it could have been because these operations are all privileged and root already has     enormous destructive power. (CVE-2020-12652)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote OracleVM system is missing necessary patches to address security updates:

  - A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before     4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection     negotiation during the handling of the remote devices country settings. This could allow the remote device     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2019-14895)

  - ext4_empty_dir in fs/ext4/namei.c in the Linux kernel through 5.3.12 allows a NULL pointer dereference     because ext4_read_dirblock(inode,0,DIRENT_HTREE) can be zero. (CVE-2019-19037)

  - In the Linux kernel 5.0.21, mounting a crafted ext4 filesystem image, performing some operations, and     unmounting can lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list     in fs/ext4/super.c. (CVE-2019-19447)

  - An issue was discovered in the Linux kernel before 5.2.6. On NUMA systems, the Linux fair scheduler has a     use-after-free in show_numa_stats() because NUMA fault statistics are inappropriately freed, aka     CID-16d51a590a8c. (CVE-2019-20934)

  - A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7.
    This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into     the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO     restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate     that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer     dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network     user to crash the system kernel, resulting in a denial of service. (CVE-2020-10711)

  - usb_sg_cancel in drivers/usb/core/message.c in the Linux kernel before 5.6.8 has a use-after-free because     a transfer occurs without a reference, aka CID-056ad39ee925. (CVE-2020-12464)

  - The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows     local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a     double fetch vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states The security impact of this     bug is not as bad as it could have been because these operations are all privileged and root already has     enormous destructive power. (CVE-2020-12652)

  - An out-of-bounds memory write flaw was found in how the Linux kernel's Voice Over IP H.323 connection     tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote     user to crash the system, causing a denial of service. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-14305)

  - A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem     allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate     privileges. The highest threat from this vulnerability is to data confidentiality and integrity as well as     system availability. (CVE-2020-14351)

  - Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain     privileges or cause a denial of service by leveraging improper access to a certain error field.
    (CVE-2020-15436)

  - A flaw was found in Linux Kernel because access to the global variable fg_console is not properly     synchronized leading to a use after free in con_font_op. (CVE-2020-25668)

  - A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw     allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that     relies on UDP source port randomization are indirectly affected as well on the Linux Based Products     (RUGGEDCOM RM1224: All versions between v5.0 and v6.4, SCALANCE M-800: All versions between v5.0 and v6.4,     SCALANCE S615: All versions between v5.0 and v6.4, SCALANCE SC-600: All versions prior to v2.1.3, SCALANCE     W1750D: v8.3.0.1, v8.6.0, and v8.7.0, SIMATIC Cloud Connect 7: All versions, SIMATIC MV500 Family: All     versions, SIMATIC NET CP 1243-1 (incl. SIPLUS variants): Versions 3.1.39 and later, SIMATIC NET CP 1243-7     LTE EU: Version (CVE-2020-25705)

  - A buffer over-read (at the framebuffer layer) in the fbcon code in the Linux kernel before 5.8.15 could be     used by local attackers to read kernel memory, aka CID-6735b4632def. (CVE-2020-28915)

  - A slab-out-of-bounds read in fbcon in the Linux kernel before 5.9.7 could be used by local attackers to     read privileged information or potentially crash the kernel, aka CID-3c4e0dff2095. This occurs because     KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for manipulations such as font height. (CVE-2020-28974)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This update syncs the RT kernel from the SUSE Linux Enterprise 15-SP2 codestream. This update was imported from the SUSE:SLE-15-SP2:Update update project.

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14393-1 advisory.

  - Incomplete cleanup from specific special register read operations in some Intel(R) Processors may allow an     authenticated user to potentially enable information disclosure via local access. (CVE-2020-0543)

  - There is a use-after-free in kernel versions before 5.5 due to a race condition between the release of     ptp_clock and cdev while resource deallocation. When a (high privileged) process allocates a ptp device     file (like /dev/ptpX) and voluntarily goes to sleep. During this time if the underlying device is removed,     it can cause an exploitable condition as the process wakes up to terminate and clean all attached files.
    The system crashes due to the cdev structure being invalid (as already freed) which is pointed to by the     inode. (CVE-2020-10690)

  - The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows     local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a     double fetch vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states The security impact of this     bug is not as bad as it could have been because these operations are all privileged and root already has     enormous destructive power. (CVE-2020-12652)

  - An issue was found in Linux kernel before 5.5.4. The mwifiex_cmd_append_vsie_tlv() function in     drivers/net/wireless/marvell/mwifiex/scan.c allows local users to gain privileges or cause a denial of     service because of an incorrect memcpy and buffer overflow, aka CID-b70261a288ea. (CVE-2020-12653)

  - An issue was found in Linux kernel before 5.5.4. mwifiex_ret_wmm_get_status() in     drivers/net/wireless/marvell/mwifiex/wmm.c allows a remote AP to trigger a heap-based buffer overflow     because of an incorrect memcpy, aka CID-3a9b153c5591. (CVE-2020-12654)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A flaw was found in the Linux kernel's implementation     of GRO. This flaw allows an attacker with local access     to crash the system.(CVE-2020-10720)

  - A NULL pointer dereference flaw was found in the Linux     kernel's SELinux subsystem. This flaw occurs while     importing the Commercial IP Security Option (CIPSO)     protocol's category bitmap into the SELinux extensible     bitmap via the' ebitmap_netlbl_import' routine. While     processing the CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of     service.(CVE-2020-10711)

  - A signal access-control issue was discovered in the     Linux kernel before 5.6.5, aka CID-7395ea4e65c2.
    Because exec_id in include/linux/sched.h is only 32     bits, an integer overflow can interfere with a     do_notify_parent protection mechanism. A child process     can send an arbitrary signal to a parent process in a     different security domain. Exploitation limitations     include the amount of elapsed time before an integer     overflow occurs, and the lack of scenarios where     signals to a parent process present a substantial     operational threat.(CVE-2020-12826)

  - An issue was discovered in the Linux kernel before     5.4.17. drivers/spi/spi-dw.c allows attackers to cause     a panic via concurrent calls to dw_spi_irq and     dw_spi_transfer_one, aka     CID-19b61392c5a8.(CVE-2020-12769)

  - An issue was discovered in the Linux kernel through     5.6.11. sg_write lacks an sg_remove_request call in a     certain failure case, aka     CID-83c6f2390040.(CVE-2020-12770)

  - An issue was discovered in the Linux kernel through     5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c     has a deadlock if a coalescing operation     fails.(CVE-2020-12771)

  - The __mptctl_ioctl function in     drivers/message/fusion/mptctl.c in the Linux kernel     before 5.4.14 allows local users to hold an incorrect     lock during the ioctl operation and trigger a race     condition, i.e., a 'double fetch' vulnerability, aka     CID-28d76df18f0a. NOTE: the vendor states 'The security     impact of this bug is not as bad as it could have been     because these operations are all privileged and root     already has enormous destructive     power.'(CVE-2020-12652)

  - An issue was discovered in xfs_agf_verify in     fs/xfs/libxfs/xfs_alloc.c in the Linux kernel through     5.6.10. Attackers may trigger a sync of excessive     duration via an XFS v5 image with crafted metadata, aka     CID-d0c7feaf8767.(CVE-2020-12655)

  - A pivot_root race condition in fs amespace.c in the     Linux kernel 4.4.x before 4.4.221, 4.9.x before     4.9.221, 4.14.x before 4.14.178, 4.19.x before     4.19.119, and 5.x before 5.3 allows local users to     cause a denial of service (panic) by corrupting a     mountpoint reference counter.(CVE-2020-12114)

The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2020:14442-1 advisory.

  - An exploitable denial-of-service vulnerability exists in the Linux kernel prior to mainline 5.3. An     attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations     before the required authentication process has completed. This could lead to different denial-of-service     scenarios, either by causing CAM table attacks, or by leading to traffic flapping if faking already     existing clients in other nearby APs of the same wireless infrastructure. An attacker can forge     Authentication and Association Request packets to trigger this vulnerability. (CVE-2019-5108)

  - In cdev_get of char_dev.c, there is a possible use-after-free due to a race condition. This could lead to     local escalation of privilege with System execution privileges needed. User interaction is not needed for     exploitation.Product: AndroidVersions: Android-10Android ID: A-153467744 (CVE-2020-0305)

  - A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an     attacker with a local account to crash a trivial program and exfiltrate private kernel data.
    (CVE-2020-10732)

  - A buffer over-read flaw was found in RH kernel versions before 5.0 in crypto_authenc_extractkeys in     crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. When a payload longer than 4     bytes, and is not following 4-byte alignment boundary guidelines, it causes a buffer over-read threat,     leading to a system crash. This flaw allows a local attacker with user privileges to cause a denial of     service. (CVE-2020-10769)

  - A stack information leak flaw was found in s390/s390x in the Linux kernels memory manager functionality,     where it incorrectly writes to the /proc/sys/vm/cmm_timeout file. This flaw allows a local user to see the     kernel data. (CVE-2020-10773)

  - The __mptctl_ioctl function in drivers/message/fusion/mptctl.c in the Linux kernel before 5.4.14 allows     local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a     double fetch vulnerability, aka CID-28d76df18f0a. NOTE: the vendor states The security impact of this     bug is not as bad as it could have been because these operations are all privileged and root already has     enormous destructive power. (CVE-2020-12652)

  - ** DISPUTED ** gss_mech_free in net/sunrpc/auth_gss/gss_mech_switch.c in the rpcsec_gss_krb5     implementation in the Linux kernel through 5.6.10 lacks certain domain_release calls, leading to a memory     leak. Note: This was disputed with the assertion that the issue does not grant any access not already     available. It is a problem that on unloading a specific kernel module some memory is leaked, but loading     kernel modules is a privileged operation. A user could also write a kernel module to consume any amount of     memory they like and load that replicating the effect of this bug. (CVE-2020-12656)

  - An issue was discovered in the Linux kernel 4.4 through 5.7.1. drivers/tty/vt/keyboard.c has an integer     overflow if k_ascii is called several times in a row, aka CID-b86dab054059. NOTE: Members in the community     argue that the integer overflow does not lead to a security issue in this case. (CVE-2020-13974)

  - In the Linux kernel before 5.4.16, a race condition in tty->disc_data handling in the slip and slcan line     discipline could lead to a use-after-free, aka CID-0ace17d56824. This affects drivers/net/slip/slip.c and     drivers/net/can/slcan.c. (CVE-2020-14416)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to the versions of the kernel packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

  - The kernel package contains the Linux kernel (vmlinuz),     the core of any Linux operating system. The kernel     handles the basic functions of the operating system:
    memory allocation, process allocation, device input and     output, etc. Security Fix(es):In the Android kernel in     F2FS driver there is a possible out of bounds read due     to a missing bounds check. This could lead to local     information disclosure with system execution privileges     needed. User interaction is not needed for     exploitation.(CVE-2019-9445)In calc_vm_may_flags of     ashmem.c, there is a possible arbitrary write to shared     memory due to a permissions bypass. This could lead to     local escalation of privilege by corrupting memory     shared between processes, with no additional execution     privileges needed. User interaction is not needed for     exploitation. Product: Android Versions: Android kernel     Android ID: A-142938932(CVE-2020-0009)A new domain     bypass transient execution attack known as Special     Register Buffer Data Sampling (SRBDS) has been found.
    This flaw allows data values from special internal     registers to be leaked by an attacker able to execute     code on any core of the CPU. An unprivileged, local     attacker can use this flaw to infer values returned by     affected instructions known to be commonly used during     cryptographic operations that rely on uniqueness,     secrecy, or both.(CVE-2020-0543)A flaw was found in the     Linux kernel's implementation of the BTRFS file system.
    A local attacker, with the ability to mount a file     system, can create a use-after-free memory fault after     the file system has been unmounted. This may lead to     memory corruption or privilege     escalation.(CVE-2019-19377)A NULL pointer dereference     flaw may occur in the Linux kernel's relay_open in     kernel/relay.c. if the alloc_percpu() function is not     validated in time of failure and used as a valid     address for access. An attacker could use this flaw to     cause a denial of service.(CVE-2019-19462)A NULL     pointer dereference flaw was found in     tw5864_handle_frame function in     drivers/media/pci/tw5864/tw5864-video.c in the TW5864     Series Video media driver. The pointer 'vb' is     assigned, but not validated before its use, and can     lead to a denial of service. This flaw allows a local     attacker with special user or root privileges to crash     the system or leak internal kernel     information.(CVE-2019-20806)go7007_snd_init in     drivers/media/usb/go7007/snd-go7007.c in the Linux     kernel before 5.6 does not call snd_card_free for a     failure path, which causes a memory leak, aka     CID-9453264ef586.(CVE-2019-20810)An issue was     discovered in the Linux kernel before 5.0.6. In     rx_queue_add_kobject() and netdev_queue_add_kobject()     in net/coreet-sysfs.c, a reference count is mishandled,     aka CID-a3e23f719f5c.(CVE-2019-20811)A flaw was found     in the way the af_packet functionality in the Linux     kernel handled the retirement timer setting for     TPACKET_v3 when getting settings from the underlying     network device errors out. This flaw allows a local     user who can open the af_packet domain socket and who     can hit the error path, to use this vulnerability to     starve the system.(CVE-2019-20812)A NULL pointer     dereference flaw was found in the Linux kernel's     SELinux subsystem. This flaw occurs while importing the     Commercial IP Security Option (CIPSO) protocol's     category bitmap into the SELinux extensible bitmap via     the' ebitmap_netlbl_import' routine. While processing     the CIPSO restricted bitmap tag in the     'cipso_v4_parsetag_rbm' routine, it sets the security     attribute to indicate that the category bitmap is     present, even if it has not been allocated. This issue     leads to a NULL pointer dereference issue while     importing the same category bitmap into SELinux. This     flaw allows a remote network user to crash the system     kernel, resulting in a denial of     service.(CVE-2020-10711)A flaw was found in the Linux     kernel's SELinux LSM hook implementation, where it     anticipated the skb would only contain a single Netlink     message. The hook incorrectly validated the first     Netlink message in the skb only, to allow or deny the     rest of the messages within the skb with the granted     permissions and without further processing. At this     time, there is no known ability for an attacker to     abuse this flaw.(CVE-2020-10751)A flaw was found in the     Linux Kernel in versions after 4.5-rc1 in the way     mremap handled DAX Huge Pages. This flaw allows a local     attacker with access to a DAX enabled storage to     escalate their privileges on the     system.(CVE-2020-10757)A logic bug flaw was found in     the Linux kernel's implementation of SSBD. A bug in the     logic handling allows an attacker with a local account     to disable SSBD protection during a context switch when     additional speculative execution mitigations are in     place. This issue was introduced when the per     task/process conditional STIPB switching was added on     top of the existing SSBD switching. The highest threat     from this vulnerability is to     confidentiality.(CVE-2020-10766)A flaw was found in the     Linux kernel's implementation of the Enhanced IBPB     (Indirect Branch Prediction Barrier). The IBPB     mitigation will be disabled when STIBP is not available     or when the Enhanced Indirect Branch Restricted     Speculation (IBRS) is available. This flaw allows a     local attacker to perform a Spectre V2 style attack     when this configuration is active. The highest threat     from this vulnerability is to     confidentiality.(CVE-2020-10767)A flaw was found in the     prctl() function, where it can be used to enable     indirect branch speculation after it has been disabled.
    This call incorrectly reports it as being 'force     disabled' when it is not and opens the system to     Spectre v2 attacks. The highest threat from this     vulnerability is to confidentiality.(CVE-2020-10768)A     flaw was found in the ZRAM kernel module, where a user     with a local account and the ability to read the     /sys/class/zram-control/hot_add file can create ZRAM     device nodes in the /dev/ directory. This read     allocates kernel memory and is not accounted for a user     that triggers the creation of that ZRAM device. With     this vulnerability, continually reading the device may     consume a large amount of system memory and cause the     Out-of-Memory (OOM) killer to activate and terminate     random userspace processes, possibly making the system     inoperable.(CVE-2020-10781)A stack buffer overflow     issue was found in the get_raw_socket() routine of the     Host kernel accelerator for virtio net (vhost-net)     driver. It could occur while doing an     ictol(VHOST_NET_SET_BACKEND) call, and retrieving     socket name in a kernel stack variable via     get_raw_socket(). A user able to perform ioctl(2) calls     on the '/dev/vhost-net' device may use this flaw to     crash the kernel resulting in DoS     issue.(CVE-2020-10942)A flaw was found in the Linux     kernel's implementation of the pivot_root syscall. This     flaw allows a local privileged user (root outside or     root inside a privileged container) to exploit a race     condition to manipulate the reference count of the root     filesystem. To be able to abuse this flaw, the process     or user calling pivot_root must have advanced     permissions. The highest threat from this vulnerability     is to system availability.(CVE-2020-12114)A     use-after-free flaw was found in usb_sg_cancel in     drivers/usb/core/message.c in the USB core subsystem.
    This flaw allows a local attacker with a special user     or root privileges to crash the system due to a race     problem in the scatter-gather cancellation and transfer     completion in usb_sg_wait. This vulnerability can also     lead to a leak of internal kernel     information.(CVE-2020-12464)A memory overflow and data     corruption flaw were found in the Mediatek MT76 driver     module for WiFi in mt76_add_fragment in     driverset/wireless/mediatek/mt76/dma.c. An oversized     packet with too many rx fragments causes an overflow     and corruption in memory of adjacent pages. A local     attacker with a special user or root privileges can     cause a denial of service or a leak of internal kernel     information.(CVE-2020-12465)A vulnerability was found     in __mptctl_ioctl in drivers/message/fusion/mptctl.c in     Fusion MPT base driver 'mptctl' in the SCSI device     module, where an incorrect lock leads to a race     problem. This flaw allows an attacker with local access     and special user (or root) privileges to cause a denial     of service.(CVE-2020-12652)A flaw was found in the way     the mwifiex_cmd_append_vsie_tlv() in Linux kernel's     Marvell WiFi-Ex driver handled vendor specific     information elements. A local user could use this flaw     to escalate their privileges on the     system.(CVE-2020-12653)A flaw was found in the Linux     kernel. The Marvell mwifiex driver allows a remote WiFi     access point to trigger a heap-based memory buffer     overflow due to an incorrect memcpy operation. The     highest threat from this vulnerability is to data     integrity and system availability.(CVE-2020-12654)A     flaw was discovered in the XFS source in the Linux     kernel. This flaw allows an attacker with the ability     to mount an XFS filesystem, to trigger a denial of     service while attempting to sync a file located on an     XFS v5 image with crafted metadata.(CVE-2020-12655)An     out-of-bounds (OOB) memory access flaw was found in the     Network XDP (the eXpress Data Path) module in the Linux     kernel's xdp_umem_reg function in net/xdp/xdp_umem.c.
    When a user with special user privilege of     CAP_NET_ADMIN (or root) calls setsockopt to register     umem ring on XDP socket, passing the headroom value     larger than the available space in the chunk, it leads     to an out-of-bounds write, causing panic or possible     memory corruption. This flaw may lead to privilege     escalation if a local end-user is granted permission to     influence the execution of code in this     manner.(CVE-2020-12659)A vulnerability was found in     sg_write in drivers/scsi/sg.c in the SCSI generic (sg)     driver subsystem. This flaw allows an attacker with     local access and special user or root privileges to     cause a denial of service if the allocated list is not     cleaned with an invalid (Sg_fd * sfp) pointer at the     time of failure, also possibly causing a kernel     internal information leak problem.(CVE-2020-12770)An     issue was discovered in the Linux kernel through     5.6.11. btree_gc_coalesce in drivers/md/bcache/btree.c     has a deadlock if a coalescing operation     fails.(CVE-2020-12771)A flaw was found in the Linux     kernel loose validation of child/parent process     identification handling while filtering signal     handlers. A local attacker is able to abuse this flaw     to bypass checks to send any signal to a privileged     process.(CVE-2020-12826)A flaw was found in the Linux     kernel, where it allows userspace processes, for     example, a guest VM, to directly access h/w devices via     its VFIO driver modules. The VFIO modules allow users     to enable or disable access to the devices' MMIO memory     address spaces. If a user attempts to access the     read/write devices' MMIO address space when it is     disabled, some h/w devices issue an interrupt to the     CPU to indicate a fatal error condition, crashing the     system. This flaw allows a guest user or process to     crash the host system resulting in a denial of     service.(CVE-2020-12888)gadget_dev_desc_UDC_store in     drivers/usb/gadget/configfs.c in the Linux kernel     through 5.6.13 relies on kstrdup without considering     the possibility of an internal '\0' value, which allows     attackers to trigger an out-of-bounds read, aka     CID-15753588bcd4.(CVE-2020-13143)** DISPUTED ** An     issue was discovered in the Linux kernel through 5.7.1.
    drivers/tty/vt/keyboard.c has an integer overflow if     k_ascii is called several times in a row, aka     CID-b86dab054059. NOTE: Members in the community argue     that the integer overflow does not lead to a security     issue in this case.(CVE-2020-13974)A use-after-free     flaw was found in slcan_write_wakeup in     driverset/can/slcan.c in the serial CAN module slcan. A     race condition occurs when communicating with can using     slcan between the write (scheduling the transmit) and     closing (flushing out any pending queues) the SLCAN     channel. This flaw allows a local attacker with special     user or root privileges to cause a denial of service or     a kernel information leak. The highest threat from this     vulnerability is to system     availability.(CVE-2020-14416)In the Linux kernel     through 5.7.6, usbtest_disconnect in     drivers/usb/misc/usbtest.c has a memory leak, aka     CID-28ebeb8db770.(CVE-2020-15393)The Linux kernel     through 5.7.11 allows remote attackers to make     observations that help to obtain sensitive information     about the internal state of the network RNG, aka     CID-f227e3ec3b5c. This is related to     drivers/char/random.c and     kernel/time/timer.c.(CVE-2020-16166)A flaw was found in     the Linux kernel's implementation of Userspace core     dumps. This flaw allows an attacker with a local     account to crash a trivial program and exfiltrate     private kernel data.(CVE-2020-10732)A flaw null pointer     dereference in the Linux kernel cgroupv2 subsystem in     versions before 5.7.10 was found in the way when reboot     the system. A local user could use this flaw to crash     the system or escalate their privileges on the     system.(CVE-2020-14356)The Linux kernel 4.9.x before     4.9.233, 4.14.x before 4.14.194, and 4.19.x before     4.19.140 has a use-after-free because skcd->no_refcnt     was not considered during a backport of a     CVE-2020-14356 patch. This is related to the cgroups     feature.(CVE-2020-25220)get_gate_page in mm/gup.c in     the Linux kernel 5.7.x and 5.8.x before 5.8.7 allows     privilege escalation because of incorrect reference     counting (caused by gate page mishandling) of the     struct page that backs the vsyscall page. The result is     a refcount underflow. This can be triggered by any     64-bit process that can use ptrace() or     process_vm_readv(), aka     CID-9fa2dd946743.(CVE-2020-25221)In the Linux kernel     through 5.8.7, local attackers able to inject conntrack     netlink configuration could overflow a local buffer,     causing crashes or triggering use of incorrect protocol     numbers in ctnetlink_parse_tuple_filter in     net/netfilter/nf_conntrack_netlink.c, aka     CID-1cc5ef91d2ff.(CVE-2020-25211)A buffer over-read     flaw was found in RH kernel versions before 5.0 in     crypto_authenc_extractkeys in crypto/authenc.c in the     IPsec Cryptographic algorithm's module, authenc. When a     payload longer than 4 bytes, and is not following     4-byte alignment boundary guidelines, it causes a     buffer over-read threat, leading to a system crash.
    This flaw allows a local attacker with user privileges     to cause a denial of service.(CVE-2020-10769)A flaw was     found in the Linux kernel's implementation of the     invert video code on VGA consoles when a local attacker     attempts to resize the console, calling an ioctl     VT_RESIZE, which causes an out-of-bounds write to     occur. This flaw allows a local user with access to the     VGA console to crash the system, potentially escalating     their privileges on the system. The highest threat from     this vulnerability is to data confidentiality and     integrity as well as system     availability.(CVE-2020-14331)In cdev_get of char_dev.c,     there is a possible use-after-free due to a race     condition. This could lead to local escalation of     privilege with System execution privileges needed. User     interaction is not needed for exploitation.Product:

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

  - CVE-2019-2182     Hanjun Guo and Lei Li reported a race condition in the     arm64 virtual memory management code, which could lead     to an information disclosure, denial of service (crash),     or possibly privilege escalation.

  - CVE-2019-5108     Mitchell Frank of Cisco discovered that when the IEEE     802.11 (WiFi) stack was used in AP mode with roaming, it     would trigger roaming for a newly associated station     before the station was authenticated. An attacker within     range of the AP could use this to cause a denial of     service, either by filling up a switching table or by     redirecting traffic away from other stations.

  - CVE-2019-19319     Jungyeon discovered that a crafted filesystem can cause     the ext4 implementation to deallocate or reallocate     journal blocks. A user permitted to mount filesystems     could use this to cause a denial of service (crash), or     possibly for privilege escalation.

  - CVE-2019-19462     The syzbot tool found a missing error check in the     'relay' library used to implement various files under     debugfs. A local user permitted to access debugfs could     use this to cause a denial of service (crash) or     possibly for privilege escalation.

  - CVE-2019-19768     Tristan Madani reported a race condition in the blktrace     debug facility that could result in a use-after-free. A     local user able to trigger removal of block devices     could possibly use this to cause a denial of service     (crash) or for privilege escalation.

  - CVE-2019-20806     A potential NULL pointer dereference was discovered in     the tw5864 media driver. The security impact of this is     unclear.

  - CVE-2019-20811     The Hulk Robot tool found a reference-counting bug in an     error path in the network subsystem. The security impact     of this is unclear.

  - CVE-2020-0543     Researchers at VU Amsterdam discovered that on some     Intel CPUs supporting the RDRAND and RDSEED     instructions, part of a random value generated by these     instructions may be used in a later speculative     execution on any core of the same physical CPU.
    Depending on how these instructions are used by     applications, a local user or VM guest could use this to     obtain sensitive information such as cryptographic keys     from other users or VMs.

  This vulnerability can be mitigated by a microcode update, either as   part of system firmware (BIOS) or through the intel-microcode   package in Debian's non-free archive section. This kernel update   only provides reporting of the vulnerability and the option to   disable the mitigation if it is not needed.

  - CVE-2020-2732     Paulo Bonzini discovered that the KVM implementation for     Intel processors did not properly handle instruction     emulation for L2 guests when nested virtualization is     enabled. This could allow an L2 guest to cause privilege     escalation, denial of service, or information leaks in     the L1 guest.

  - CVE-2020-8428     Al Viro discovered a potential use-after-free in the     filesystem core (vfs). A local user could exploit this     to cause a denial of service (crash) or possibly to     obtain sensitive information from the kernel.

  - CVE-2020-8647, CVE-2020-8649     The Hulk Robot tool found a potential MMIO out-of-bounds     access in the vgacon driver. A local user permitted to     access a virtual terminal (/dev/tty1 etc.) on a system     using the vgacon driver could use this to cause a denial     of service (crash or memory corruption) or possibly for     privilege escalation.

  - CVE-2020-8648     The syzbot tool found a race condition in the the     virtual terminal driver, which could result in a     use-after-free. A local user permitted to access a     virtual terminal could use this to cause a denial of     service (crash or memory corruption) or possibly for     privilege escalation.

  - CVE-2020-9383     Jordy Zomer reported an incorrect range check in the     floppy driver which could lead to a static out-of-bounds     access. A local user permitted to access a floppy drive     could use this to cause a denial of service (crash or     memory corruption) or possibly for privilege escalation.

  - CVE-2020-10711     Matthew Sheets reported NULL pointer dereference issues     in the SELinux subsystem while receiving CIPSO packet     with null category. A remote attacker can take advantage     of this flaw to cause a denial of service (crash). Note     that this issue does not affect the binary packages     distributed in Debian as CONFIG_NETLABEL is not enabled.

  - CVE-2020-10732     An information leak of kernel private memory to     userspace was found in the kernel's implementation of     core dumping userspace processes.

  - CVE-2020-10751     Dmitry Vyukov reported that the SELinux subsystem did     not properly handle validating multiple messages, which     could allow a privileged attacker to bypass SELinux     netlink restrictions.

  - CVE-2020-10757     Fan Yang reported a flaw in the way mremap handled DAX     hugepages, allowing a local user to escalate their     privileges

  - CVE-2020-10942     It was discovered that the vhost_net driver did not     properly validate the type of sockets set as back-ends.
    A local user permitted to access /dev/vhost-net could     use this to cause a stack corruption via crafted system     calls, resulting in denial of service (crash) or     possibly privilege escalation.

  - CVE-2020-11494     It was discovered that the slcan (serial line CAN)     network driver did not fully initialise CAN headers for     received packets, resulting in an information leak from     the kernel to user-space or over the CAN network.

  - CVE-2020-11565     Entropy Moe reported that the shared memory filesystem     (tmpfs) did not correctly handle an 'mpol' mount option     specifying an empty node list, leading to a stack-based     out-of-bounds write. If user namespaces are enabled, a     local user could use this to cause a denial of service     (crash) or possibly for privilege escalation.

  - CVE-2020-11608, CVE-2020-11609, CVE-2020-11668     It was discovered that the ov519, stv06xx, and     xirlink_cit media drivers did not properly validate USB     device descriptors. A physically present user with a     specially constructed USB device could use this to cause     a denial-of-service (crash) or possibly for privilege     escalation.

  - CVE-2020-12114     Piotr Krysiuk discovered a race condition between the     umount and pivot_root operations in the filesystem core     (vfs). A local user with the CAP_SYS_ADMIN capability in     any user namespace could use this to cause a denial of     service (crash).

  - CVE-2020-12464     Kyungtae Kim reported a race condition in the USB core     that can result in a use-after-free. It is not clear how     this can be exploited, but it could result in a denial     of service (crash or memory corruption) or privilege     escalation.

  - CVE-2020-12652     Tom Hatskevich reported a bug in the mptfusion storage     drivers. An ioctl handler fetched a parameter from user     memory twice, creating a race condition which could     result in incorrect locking of internal data structures.
    A local user permitted to access /dev/mptctl could use     this to cause a denial of service (crash or memory     corruption) or for privilege escalation.

  - CVE-2020-12653     It was discovered that the mwifiex WiFi driver did not     sufficiently validate scan requests, resulting a     potential heap buffer overflow. A local user with     CAP_NET_ADMIN capability could use this to cause a     denial of service (crash or memory corruption) or     possibly for privilege escalation.

  - CVE-2020-12654     It was discovered that the mwifiex WiFi driver did not     sufficiently validate WMM parameters received from an     access point (AP), resulting a potential heap buffer     overflow. A malicious AP could use this to cause a     denial of service (crash or memory corruption) or     possibly to execute code on a vulnerable system.

  - CVE-2020-12770     It was discovered that the sg (SCSI generic) driver did     not correctly release internal resources in a particular     error case. A local user permitted to access an sg     device could possibly use this to cause a denial of     service (resource exhaustion).

  - CVE-2020-13143     Kyungtae Kim reported a potential heap out-of-bounds     write in the USB gadget subsystem. A local user     permitted to write to the gadget configuration     filesystem could use this to cause a denial of service     (crash or memory corruption) or potentially for     privilege escalation.
