The SUSE Linux Enterprise 12 kernel was updated to 3.12.61 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2017-16939: The XFRM dump policy implementation in     net/xfrm/xfrm_user.c in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) via a crafted SO_RCVBUF setsockopt     system call in conjunction with XFRM_MSG_GETPOLICY     Netlink messages (bnc#1069702 1069708).

  - CVE-2017-1000405: The Linux Kernel had a problematic use     of pmd_mkdirty() in the touch_pmd() function inside the     THP implementation. touch_pmd() could be reached by     get_user_pages(). In such case, the pmd would become     dirty. This scenario breaks the new     can_follow_write_pmd()'s logic - pmd could become dirty     without going through a COW cycle. This bug was not as     severe as the original 'Dirty cow' because an ext4 file     (or any other regular file) could not be mapped using     THP. Nevertheless, it did allow us to overwrite     read-only huge pages. For example, the zero huge page     and sealed shmem files could be overwritten (since their     mapping could be populated using THP). Note that after     the first write page-fault to the zero page, it will be     replaced with a new fresh (and zeroed) thp (bnc#1069496     1070307).

  - CVE-2017-16649: The usbnet_generic_cdc_bind function in     drivers/net/usb/cdc_ether.c in the Linux kernel allowed     local users to cause a denial of service (divide-by-zero     error and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1067085).

  - CVE-2014-0038: The compat_sys_recvmmsg function in     net/compat.c in the Linux kernel, when CONFIG_X86_X32 is     enabled, allowed local users to gain privileges via a     recvmmsg system call with a crafted timeout pointer     parameter (bnc#860993).

  - CVE-2017-16650: The qmi_wwan_bind function in     drivers/net/usb/qmi_wwan.c in the Linux kernel allowed     local users to cause a denial of service (divide-by-zero     error and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1067086).

  - CVE-2017-16535: The usb_get_bos_descriptor function in     drivers/usb/core/config.c in the Linux kernel allowed     local users to cause a denial of service (out-of-bounds     read and system crash) or possibly have unspecified     other impact via a crafted USB device (bnc#1066700).

  - CVE-2017-15102: The tower_probe function in     drivers/usb/misc/legousbtower.c in the Linux kernel     allowed local users (who are physically proximate for     inserting a crafted USB device) to gain privileges by     leveraging a write-what-where condition that occurs     after a race condition and a NULL pointer dereference     (bnc#1066705).

  - CVE-2017-16531: drivers/usb/core/config.c in the Linux     kernel allowed local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB device,     related to the USB_DT_INTERFACE_ASSOCIATION descriptor     (bnc#1066671).

  - CVE-2017-12193: The     assoc_array_insert_into_terminal_node function in     lib/assoc_array.c in the Linux kernel mishandled node     splitting, which allowed local users to cause a denial     of service (NULL pointer dereference and panic) via a     crafted application, as demonstrated by the keyring key     type, and key addition and link creation operations     (bnc#1066192).

  - CVE-2017-16529: The snd_usb_create_streams function in     sound/usb/card.c in the Linux kernel allowed local users     to cause a denial of service (out-of-bounds read and     system crash) or possibly have unspecified other impact     via a crafted USB device (bnc#1066650).

  - CVE-2017-16525: The usb_serial_console_disconnect     function in drivers/usb/serial/console.c in the Linux     kernel allowed local users to cause a denial of service     (use-after-free and system crash) or possibly have     unspecified other impact via a crafted USB device,     related to disconnection and failed setup (bnc#1066618).

  - CVE-2017-16537: The imon_probe function in     drivers/media/rc/imon.c in the Linux kernel allowed     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     (bnc#1066573).

  - CVE-2017-16536: The cx231xx_usb_probe function in     drivers/media/usb/cx231xx/cx231xx-cards.c in the Linux     kernel allowed 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     (bnc#1066606).

  - CVE-2017-16527: sound/usb/mixer.c in the Linux kernel     allowed local users to cause a denial of service     (snd_usb_mixer_interrupt use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device (bnc#1066625).

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

CVE-2016-10208

Sergej Schumilo and Ralf Spenneberg discovered that a crafted ext4 filesystem could trigger memory corruption when it is mounted. A user that can provide a device or filesystem image to be mounted could use this for denial of service (crash or data corruption) or possibly for privilege escalation.

CVE-2017-8824

Mohamed Ghannam discovered that the DCCP implementation did not correctly manage resources when a socket is disconnected and reconnected, potentially leading to a use-after-free. A local user could use this for denial of service (crash or data corruption) or possibly for privilege escalation. On systems that do not already have the dccp module loaded, this can be mitigated by disabling it: echo >> /etc/modprobe.d/disable-dccp.conf install dccp false

CVE-2017-8831

Pengfei Wang discovered that the saa7164 video capture driver re-reads data from a PCI device after validating it. A physically present user able to attach a specially designed PCI device could use this for privilege escalation.

CVE-2017-12190

Vitaly Mayatskikh discovered that the block layer did not correctly count page references for raw I/O from user-space. This can be exploited by a guest VM with access to a host SCSI device for denial of service (memory exhaustion) or potentially for privilege escalation.

CVE-2017-13080

A vulnerability was found in the WPA2 protocol that could lead to reinstallation of the same Group Temporal Key (GTK), which substantially reduces the security of wifi encryption. This is one of the issues collectively known as 'KRACK'.

Updates to GTKs are usually handled by the wpa package, where this issue was already fixed (DLA-1150-1). However, some wifi devices can remain active and update GTKs autonomously while the system is suspended. The kernel must also check for and ignore key reinstallation.

CVE-2017-14051

'shqking' reported that the qla2xxx SCSI host driver did not correctly validate I/O to the 'optrom' sysfs attribute of the devices it creates. This is unlikely to have any security impact.

CVE-2017-15115

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 ipx_recvmsg function in net/ipx/af_ipx.c in the     Linux kernel before 3.12.4 updates a certain length     value without ensuring that an associated data     structure has been initialized, which allows local     users to obtain sensitive information from kernel     memory via a (1) recvfrom, (2) recvmmsg, or (3) recvmsg     system call.(CVE-2013-7268i1/4%0

  - The move_pages system call in mm/migrate.c in the Linux     kernel doesn't check the effective uid of the target     process. This enables a local attacker to learn the     memory layout of a setuid executable allowing     mitigation of ASLR.(CVE-2017-14140i1/4%0

  - Multiple array index errors in drivers/hid/hid-core.c     in the Human Interface Device (HID) subsystem in the     Linux kernel through 3.11 allow physically proximate     attackers to execute arbitrary code or cause a denial     of service (heap memory corruption) via a crafted     device that provides an invalid Report     ID.(CVE-2013-2888i1/4%0

  - It was found that if a Non-Maskable Interrupt (NMI)     occurred immediately after a SYSCALL call or before a     SYSRET call with the user RSP pointing to the NMI IST     stack, the kernel could skip that NMI.(CVE-2015-3291i1/4%0

  - The sound/core/seq_device.c in the Linux kernel, before     4.13.4, allows local users to cause a denial of service     (snd_rawmidi_dev_seq_free use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16528i1/4%0

  - net/ceph/auth_x.c in Ceph, as used in the Linux kernel     before 3.16.3, does not properly consider the     possibility of kmalloc failure, which allows remote     attackers to cause a denial of service (system crash)     or possibly have unspecified other impact via a long     unencrypted auth ticket.(CVE-2014-6417i1/4%0

  - A NULL pointer dereference flaw was found in the Linux     kernel: the NFSv4.2 migration code improperly     initialized the kernel structure. A local,     authenticated user could use this flaw to cause a panic     of the NFS client (denial of service).(CVE-2015-8746i1/4%0

  - A stack-based buffer overflow flaw was found in the     TechnoTrend/Hauppauge DEC USB device driver. A local     user with write access to the corresponding device     could use this flaw to crash the kernel or,     potentially, elevate their privileges on the     system.(CVE-2014-8884i1/4%0

  - A flaw was found in the linux kernel's implementation     of the airspy USB device driver in which a leak was     found when a subdev or SDR are plugged into the host.An     attacker can create an targeted USB device which can     emulate 64 of these devices. Then by emulating an     additional device which continuously connects and     disconnects, each connection attempt will leak memory     which can not be recovered.(CVE-2016-5400i1/4%0

  - The sound/usb/mixer.c in the Linux kernel, before     4.13.8, allows local users to cause a denial of service     (snd_usb_mixer_interrupt use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16527i1/4%0

  - The Human Interface Device (HID) subsystem in the Linux     kernel through 3.11, when CONFIG_LOGITECH_FF,     CONFIG_LOGIG940_FF, or CONFIG_LOGIWHEELS_FF is enabled,     allows physically proximate attackers to cause a denial     of service (heap-based out-of-bounds write) via a     crafted device, related to (1) drivers/hid/hid-lgff.c,     (2) drivers/hid/hid-lg3ff.c, and (3)     drivers/hid/hid-lg4ff.c.(CVE-2013-2893i1/4%0

  - It was found that reporting emulation failures to user     space could lead to either a local (CVE-2014-7842) or a     L2-i1/4zL1 (CVE-2010-5313) denial of service. In the case     of a local denial of service, an attacker must have     access to the MMIO area or be able to access an I/O     port. Please note that on certain systems, HPET is     mapped to userspace as part of vdso (vvar) and thus an     unprivileged user may generate MMIO transactions (and     enter the emulator) this way.(CVE-2014-7842i1/4%0

  - A flaw was discovered in the way the Linux kernel's TTY     subsystem handled the tty shutdown phase. A local,     unprivileged user could use this flaw to cause denial     of service on the system by holding a reference to the     ldisc lock during tty shutdown, causing a     deadlock.(CVE-2015-4170i1/4%0

  - The __ip6_append_data function in net/ipv6/ip6_output.c     in the Linux kernel through 4.11.3 is too late in     checking whether an overwrite of an skb data structure     may occur, which allows local users to cause a denial     of service (system crash) via crafted system     calls.(CVE-2017-9242i1/4%0

  - The Linux kernel built with the KVM visualization     support (CONFIG_KVM), with nested visualization(nVMX)     feature enabled (nested=1), was vulnerable to a stack     buffer overflow issue. The vulnerability could occur     while traversing guest page table entries to resolve     guest virtual address(gva). An L1 guest could use this     flaw to crash the host kernel resulting in denial of     service (DoS) or potentially execute arbitrary code on     the host to gain privileges on the     system.(CVE-2017-12188i1/4%0

  - The recalculate_apic_map function in     arch/x86/kvm/lapic.c in the KVM subsystem in the Linux     kernel through 3.12.5 allows guest OS users to cause a     denial of service (host OS crash) via a crafted ICR     write operation in x2apic mode.(CVE-2013-6376i1/4%0

  - The wanxl_ioctl function in drivers/net/wan/wanxl.c in     the Linux kernel before 3.11.7 does not properly     initialize a certain data structure, which allows local     users to obtain sensitive information from kernel     memory via an ioctl call.(CVE-2014-1445i1/4%0

  - The restore_fpu_checking function in     arch/x86/include/asm/fpu-internal.h in the Linux kernel     before 3.12.8 on the AMD K7 and K8 platforms does not     clear pending exceptions before proceeding to an EMMS     instruction, which allows local users to cause a denial     of service (task kill) or possibly gain privileges via     a crafted application.(CVE-2014-1438i1/4%0

  - A race condition was found in the way the Linux     kernel's memory subsystem handled the copy-on-write     (COW) breakage of private read-only memory mappings. An     unprivileged, local user could use this flaw to gain     write access to otherwise read-only memory mappings and     thus increase their privileges on the     system.(CVE-2016-5195i1/4%0

  - Algorithms not compatible with mcryptd could be spawned     by mcryptd with a direct crypto_alloc_tfm invocation     using a 'mcryptd(alg)' name construct. This causes     mcryptd to crash the kernel if an arbitrary 'alg' is     incompatible and not intended to be used with     mcryptd.(CVE-2016-10147i1/4%0

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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 installation on the remote host is affected by the following vulnerabilities :

  - It was found that in the Linux kernel through     v4.14-rc5, bio_map_user_iov() and bio_unmap_user() in     'block/bio.c' do unbalanced pages refcounting if IO     vector has small consecutive buffers belonging to the     same page. bio_add_pc_page() merges them into one, but     the page reference is never dropped, causing a memory     leak and possible system lockup due to out-of-memory     condition.(CVE-2017-12190)

  - A vulnerability was found in the Key Management sub     component of the Linux kernel, where when trying to     issue a KEYTCL_READ on a negative key would lead to a     NULL pointer dereference. A local attacker could use     this flaw to crash the kernel.(CVE-2017-12192)

  - A flaw was found in the Linux kernel's implementation     of associative arrays introduced in 3.13. This     functionality was backported to the 3.10 kernels in Red     Hat Enterprise Linux 7. The flaw involved a null     pointer dereference in assoc_array_apply_edit() due to     incorrect node-splitting in assoc_array implementation.
    This affects the keyring key type and thus key addition     and link creation operations may cause the kernel to     panic.(CVE-2017-12193)

  - A divide-by-zero vulnerability was found in the
    __tcp_select_window function in the Linux kernel. This     can result in a kernel panic causing a local denial of     service.(CVE-2017-14106)

  - The move_pages system call in mm/migrate.c in the Linux     kernel doesn't check the effective uid of the target     process. This enables a local attacker to learn the     memory layout of a setuid executable allowing     mitigation of ASLR.(CVE-2017-14140)

  - The iscsi_if_rx() function in     'drivers/scsi/scsi_transport_iscsi.c' in the Linux     kernel from v2.6.24-rc1 through 4.13.2 allows local     users to cause a denial of service (a system panic) by     making a number of certain syscalls by leveraging     incorrect length validation in the kernel     code.(CVE-2017-14489)

  - The sg_ioctl() function in 'drivers/scsi/sg.c' in the     Linux kernel, from version 4.12-rc1 to 4.14-rc2, allows     local users to obtain sensitive information from     uninitialized kernel heap-memory locations via an     SG_GET_REQUEST_TABLE ioctl call for     '/dev/sg0'.(CVE-2017-14991)

  - The tower_probe function in     drivers/usb/misc/legousbtower.c in the Linux kernel     before 4.8.1 allows local users (who are physically     proximate for inserting a crafted USB device) to gain     privileges by leveraging a write-what-where condition     that occurs after a race condition and a NULL pointer     dereference.(CVE-2017-15102)

  - A vulnerability was found in the Linux kernel when     peeling off an association to the socket in another     network namespace. All transports in this association     are not to be rehashed and keep using the old key in     hashtable, thus removing transports from hashtable when     closing the socket, all transports are being freed.
    Later on a use-after-free issue could be caused when     looking up an association and dereferencing the     transports.(CVE-2017-15115)

  - A use-after-free vulnerability was found in a network     namespaces code affecting the Linux kernel since     v4.0-rc1 through v4.15-rc5. The function     get_net_ns_by_id() does not check for the net::count     value after it has found a peer network in netns_ids     idr which could lead to double free and memory     corruption. This vulnerability could allow an     unprivileged local user to induce kernel memory     corruption on the system, leading to a crash. Due to     the nature of the flaw, privilege escalation cannot be     fully ruled out, although it is thought to be     unlikely.(CVE-2017-15129)

  - A use-after-free vulnerability was found when issuing     an ioctl to a sound device. This could allow a user to     exploit a race condition and create memory corruption     or possibly privilege escalation.(CVE-2017-15265)

  - A flaw was found in the implementation of associative     arrays where the add_key systemcall and KEYCTL_UPDATE     operations allowed for a NULL payload with a nonzero     length. When accessing the payload within this length     parameters value, an unprivileged user could trivially     cause a NULL pointer dereference (kernel     oops).(CVE-2017-15274)

  - A vulnerability was found in the key management     subsystem of the Linux kernel. An update on an     uninstantiated key could cause a kernel panic, leading     to denial of service (DoS).(CVE-2017-15299)

  - It was found that fanout_add() in     'net/packet/af_packet.c' in the Linux kernel, before     version 4.13.6, allows local users to gain privileges     via crafted system calls that trigger mishandling of     packet_fanout data structures, because of a race     condition (involving fanout_add and packet_do_bind)     that leads to a use-after-free bug.(CVE-2017-15649)

  - The usb_serial_console_disconnect function in     drivers/usb/serial/console.c in the Linux kernel,     before 4.13.8, allows local users to cause a denial of     service (use-after-free and system crash) or possibly     have unspecified other impact via a crafted USB device,     related to disconnection and failed     setup.(CVE-2017-16525)

  - The drivers/uwb/uwbd.c in the Linux kernel, before     4.13.6, allows local users to cause a denial of service     (general protection fault and system crash) or possibly     have unspecified other impact via a crafted USB     device.(CVE-2017-16526)

  - The sound/usb/mixer.c in the Linux kernel, before     4.13.8, allows local users to cause a denial of service     (snd_usb_mixer_interrupt use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16527)

  - The sound/core/seq_device.c in the Linux kernel, before     4.13.4, allows local users to cause a denial of service     (snd_rawmidi_dev_seq_free use-after-free and system     crash) or possibly have unspecified other impact via a     crafted USB device.(CVE-2017-16528)

  - The snd_usb_create_streams function in sound/usb/card.c     in the Linux kernel, before 4.13.6, allows local users     to cause a denial of service (out-of-bounds read and     system crash) or possibly have unspecified other impact     via a crafted USB device.(CVE-2017-16529)

  - The uas driver in the Linux kernel before 4.13.6 allows     local users to cause a denial of service (out-of-bounds     read and system crash), or possibly have unspecified     other impacts via a crafted USB device, related to     drivers/usb/storage/uas-detect.h and     drivers/usb/storage/uas.c.(CVE-2017-16530)

  - The function drivers/usb/core/config.c in the Linux     kernel, allows local users to cause a denial of service     (out-of-bounds read and system crash) or possibly have     unspecified other impact via a crafted USB device,     related to the USB_DT_INTERFACE_ASSOCIATION     descriptor.(CVE-2017-16531)

  - The get_endpoints function in     drivers/usb/misc/usbtest.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-2017-16532)
