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

  - A race condition in the store_int_with_restart()     function in arch/x86/kernel/cpu/mcheck/mce.c in the     Linux kernel allows local users to cause a denial of     service (panic) by leveraging root access to write to     the check_interval file in a     /sys/devices/system/machinecheck/machinechecki1/4^cpu     numberi1/4%0 directory.(CVE-2018-7995i1/4%0

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.

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

  - A flaw was found in the Linux kernel's client-side     implementation of the cifs protocol. This flaw allows     an attacker controlling the server to kernel panic a     client which has the CIFS server     mounted.(CVE-2018-1066)

  - In the Linux Kernel before version 4.15.8, 4.14.25,     4.9.87, 4.4.121, 4.1.51, and 3.2.102, an error in the     '_sctp_make_chunk()' function     (net/sctp/sm_make_chunk.c) when handling SCTP packets     length can be exploited to cause a kernel     crash.(CVE-2018-5803)

  - Memory leak in the sas_smp_get_phy_events function in     drivers/scsi/libsas/sas_expander.c in the Linux kernel     allows local users to cause a denial of service (kernel     memory exhaustion) via multiple read accesses to files     in the /sys/class/sas_phy directory.(CVE-2018-7757)

  - A race condition in the store_int_with_restart()     function in arch/x86/kernel/cpu/mcheck/mce.c in the     Linux kernel allows local users to cause a denial of     service (panic) by leveraging root access to write to     the check_interval file in a     /sys/devices/system/machinecheck/machinecheck (cpu     number) directory.(CVE-2018-7995)

  - ALSA sequencer core initializes the event pool on     demand by invoking snd_seq_pool_init() when the first     write happens and the pool is empty. A user can reset     the pool size manually via ioctl concurrently, and this     may lead to UAF or out-of-bound access.(CVE-2018-7566)

  - A flaw was found in the Linux kernel's implementation     of 32-bit syscall interface for bridging. This allowed     a privileged user to arbitrarily write to a limited     range of kernel memory.(CVE-2018-1068)

  - A vulnerability was found in the Linux kernel's     kernel/events/core.c:perf_cpu_time_max_percent_handler(     ) function. Local privileged users could exploit this     flaw to cause a denial of service due to integer     overflow or possibly have unspecified other     impact.(CVE-2017-18255)

  - The code in the drivers/scsi/libsas/sas_scsi_host.c     file in the Linux kernel allow a physically proximate     attacker to cause a memory leak in the ATA command     queue and, thus, denial of service by triggering     certain failure conditions.(CVE-2018-10021)

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.

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

  - The powermate_probe function in     drivers/input/misc/powermate.c in the Linux kernel     before 4.5.1 allows physically proximate attackers to     cause a denial of service (NULL pointer dereference and     system crash) via a crafted endpoints value in a USB     device descriptor.(CVE-2016-2186)

  - In ashmem_ioctl of ashmem.c, there is an out-of-bounds     write due to insufficient locking when accessing asma.
    This could lead to a local elevation of privilege     enabling code execution as a privileged process with no     additional execution privileges needed. User     interaction is not needed for exploitation. Product:
    Android. Versions: Android kernel. Android ID:
    A-66954097.(CVE-2017-13216)

  - A certain backport in the TCP Fast Open implementation     for the Linux kernel before 3.18 does not properly     maintain a count value, which allow local users to     cause a denial of service (system crash) via the Fast     Open feature, as demonstrated by visiting the     chrome://flags/#enable-tcp-fast-open URL when using     certain 3.10.x through 3.16.x kernel builds, including     longterm-maintenance releases and ckt (aka Canonical     Kernel Team) builds.(CVE-2015-3332)

  - The rtnl_fill_link_ifmap function in     net/core/rtnetlink.c in the Linux kernel before 4.5.5     does not initialize a certain data structure, which     allows local users to obtain sensitive information from     kernel stack memory by reading a Netlink     message.(CVE-2016-4486)

  - The ip6gre_err function in net/ipv6/ip6_gre.c in the     Linux kernel allows remote attackers to have     unspecified impact via vectors involving GRE flags in     an IPv6 packet, which trigger an out-of-bounds     access.(CVE-2017-5897)

  - In the Linux kernel before version 4.12, Kerberos 5     tickets decoded when using the RXRPC keys incorrectly     assumes the size of a field. This could lead to the     size-remaining variable wrapping and the data pointer     going over the end of the buffer. This could possibly     lead to memory corruption and possible privilege     escalation.(CVE-2017-7482)

  - A flaw was found in the Linux Kernel where an attacker     may be able to have an uncontrolled read to     kernel-memory from within a vm guest. A race condition     between connect() and close() function may allow an     attacker using the AF_VSOCK protocol to gather a 4 byte     information leak or possibly intercept or corrupt     AF_VSOCK messages destined to other     clients.(CVE-2018-14625)

  - drivers/net/usb/asix_devices.c in the Linux kernel     through 4.13.11 allows local users to cause a denial of     service (NULL pointer dereference and system crash) or     possibly have unspecified other impact via a crafted     USB device.(CVE-2017-16647)

  - A memory leak in the ql_alloc_large_buffers() function     in drivers/net/ethernet/qlogic/qla3xxx.c in the Linux     kernel before 5.3.5 allows local users to cause a     denial of service (memory consumption) by triggering     pci_dma_mapping_error() failures, aka     CID-1acb8f2a7a9f.(CVE-2019-18806)

  - An issue was discovered in the fd_locked_ioctl function     in drivers/block/floppy.c in the Linux kernel through     4.15.7. The floppy driver will copy a kernel pointer to     user memory in response to the FDGETPRM ioctl. An     attacker can send the FDGETPRM ioctl and use the     obtained kernel pointer to discover the location of     kernel code and data and bypass kernel security     protections such as KASLR.(CVE-2018-7755)

  - The usbvision driver in the Linux kernel package     3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red     Hat Enterprise Linux (RHEL) 7.1 allows physically     proximate attackers to cause a denial of service     (panic) via a nonzero bInterfaceNumber value in a USB     device descriptor.(CVE-2015-7833)

  - drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the     Linux kernel 5.2.14 does not check the alloc_workqueue     return value, leading to a NULL pointer     dereference.(CVE-2019-16234)

  - drivers/net/fjes/fjes_main.c in the Linux kernel 5.2.14     does not check the alloc_workqueue return value,     leading to a NULL pointer dereference.(CVE-2019-16231)

  - Insufficient access control in the Intel(R)     PROSet/Wireless WiFi Software driver before version     21.10 may allow an unauthenticated user to potentially     enable denial of service via adjacent     access.(CVE-2019-0136)

  - A flaw was found in the Linux kernel. A heap based     buffer overflow in mwifiex_uap_parse_tail_ies function     in drivers/net/wireless/marvell/mwifiex/ie.c might lead     to memory corruption and possibly other     consequences.(CVE-2019-10126)

  - The Bluetooth BR/EDR specification up to and including     version 5.1 permits sufficiently low encryption key     length and does not prevent an attacker from     influencing the key length negotiation. This allows     practical brute-force attacks (aka 'KNOB') that can     decrypt traffic and inject arbitrary ciphertext without     the victim noticing.(CVE-2019-9506)

  - An issue was discovered in net/wireless/nl80211.c in     the Linux kernel through 5.2.17. It does not check the     length of variable elements in a beacon head, leading     to a buffer overflow.(CVE-2019-16746)

  - In the hidp_process_report in bluetooth, there is an     integer overflow. This could lead to an out of bounds     write with no additional execution privileges needed.

    It was discovered that the netfilter subsystem in the Linux kernel did not validate that rules containing     jumps contained user-defined chains. A local attacker could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2018-1065)

    It was discovered that the netfilter subsystem of the Linux kernel did not properly validate ebtables     offsets. A local attacker could use this to cause a denial of service (system crash) or possibly execute     arbitrary code. (CVE-2018-1068)

    It was discovered that a null pointer dereference vulnerability existed in the DCCP protocol     implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system     crash). (CVE-2018-1130)

    It was discovered that the SCTP Protocol implementation in the Linux kernel did not properly validate     userspace provided payload lengths in some situations. A local attacker could use this to cause a denial     of service (system crash). (CVE-2018-5803)

    It was discovered that a double free error existed in the block layer subsystem of the Linux kernel when     setting up a request queue. A local attacker could use this to cause a denial of service (system crash) or     possibly execute arbitrary code. (CVE-2018-7480)

    It was discovered that a memory leak existed in the SAS driver subsystem of the Linux kernel. A local     attacker could use this to cause a denial of service (memory exhaustion). (CVE-2018-7757)

    It was discovered that a race condition existed in the x86 machine check handler in the Linux kernel. A     local privileged attacker could use this to cause a denial of service (system crash) or possibly execute     arbitrary code. (CVE-2018-7995)

    Eyal Itkin discovered that the USB displaylink video adapter driver in the Linux kernel did not properly     validate mmap offsets sent from userspace. A local attacker could use this to expose sensitive information     (kernel memory) or possibly execute arbitrary code. (CVE-2018-8781)

    Silvio Cesare discovered a buffer overwrite existed in the NCPFS implementation in the Linux kernel. A     remote attacker controlling a malicious NCPFS server could use this to cause a denial of service (system     crash) or possibly execute arbitrary code. (CVE-2018-8822)
