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

  - A use-after-free vulnerability was found in the     kernel's socket recvmmsg subsystem. This may allow     remote attackers to corrupt memory and may allow     execution of arbitrary code. This corruption takes     place during the error handling routines within
    __sys_recvmmsg() function.(CVE-2016-7117)

  - A heap-buffer overflow vulnerability was found in the     arcmsr_iop_message_xfer() function in     'drivers/scsi/arcmsr/arcmsr_hba.c' file in the Linux     kernel through 4.8.2. The function does not restrict a     certain length field, which allows local users to gain     privileges or cause a denial of service via an     ARCMSR_MESSAGE_WRITE_WQBUFFER control code. This can     potentially cause kernel heap corruption and arbitrary     kernel code execution.(CVE-2016-7425)

  - A flaw was found in the Linux kernel's implementation     of seq_file where a local attacker could manipulate     memory in the put() function pointer. This could lead     to memory corruption and possible privileged     escalation.(CVE-2016-7910)

  - A use-after-free vulnerability in sys_ioprio_get() was     found due to get_task_ioprio() accessing the     task-i1/4zio_context without holding the task lock and     could potentially race with exit_io_context(), leading     to a use-after-free.(CVE-2016-7911)

  - The xc2028_set_config function in     drivers/media/tuners/tuner-xc2028.c in the Linux kernel     before 4.6 allows local users to gain privileges or     cause a denial of service (use-after-free) via vectors     involving omission of the firmware name from a certain     data structure. Due to the nature of the flaw,     privilege escalation cannot be fully ruled out,     although we believe it is unlikely.(CVE-2016-7913)

  - The assoc_array_insert_into_terminal_node() function in     'lib/assoc_array.c' in the Linux kernel before 4.5.3     does not check whether a slot is a leaf, which allows     local users to obtain sensitive information from kernel     memory or cause a denial of service (invalid pointer     dereference and out-of-bounds read) via an application     that uses associative-array data     structures.(CVE-2016-7914)

  - The hid_input_field() function in     'drivers/hid/hid-core.c' in the Linux kernel before 4.6     allows physically proximate attackers to obtain     sensitive information from kernel memory or cause a     denial of service (out-of-bounds read) by connecting a     device.(CVE-2016-7915)

  - Race condition in the environ_read() function in     'fs/proc/base.c' in the Linux kernel before 4.5.4     allows local users to obtain sensitive information from     kernel memory by reading a '/proc/*/environ' file     during a process-setup time interval in which     environment-variable copying is     incomplete.(CVE-2016-7916)

  - A flaw was found in the Linux networking subsystem     where a local attacker with CAP_NET_ADMIN capabilities     could cause an out-of-bounds memory access by creating     a smaller-than-expected ICMP header and sending to its     destination via sendto().(CVE-2016-8399)

  - Linux kernel built with the Kernel-based Virtual     Machine (CONFIG_KVM) support is vulnerable to a null     pointer dereference flaw. It could occur on x86     platform, when emulating an undefined instruction. An     attacker could use this flaw to crash the host kernel     resulting in DoS.(CVE-2016-8630)

  - A buffer overflow vulnerability due to a lack of input     filtering of incoming fragmented datagrams was found in     the IP-over-1394 driver firewire-net in a fragment     handling code in the Linux kernel. The vulnerability     exists since firewire supported IPv4, i.e. since     version 2.6.31 (year 2009) till version v4.9-rc4. A     maliciously formed fragment with a respectively large     datagram offset would cause a memcpy() past the     datagram buffer, which would cause a system panic or     possible arbitrary code execution.The flaw requires     firewire-net module to be loaded and is remotely     exploitable from connected firewire devices, but not     over a local network.(CVE-2016-8633)

  - It was discovered that the Linux kernel since 3.6-rc1     with 'net.ipv4.tcp_fastopen' set to 1 can hit BUG()     statement in tcp_collapse() function after making a     number of certain syscalls leading to a possible system     crash.(CVE-2016-8645)

  - A vulnerability was found in the Linux kernel. An     unprivileged local user could trigger oops in     shash_async_export() by attempting to force the     in-kernel hashing algorithms into decrypting an empty     data set.(CVE-2016-8646)

  - A flaw was found in the Linux kernel key management     subsystem in which a local attacker could crash the     kernel or corrupt the stack and additional memory     (denial of service) by supplying a specially crafted     RSA key. This flaw panics the machine during the     verification of the RSA key.(CVE-2016-8650)

  - A race condition issue leading to a use-after-free flaw     was found in the way the raw packet sockets     implementation in the Linux kernel networking subsystem     handled synchronization while creating the TPACKET_V3     ring buffer. A local user able to open a raw packet     socket (requires the CAP_NET_RAW capability) could use     this flaw to elevate their privileges on the     system.(CVE-2016-8655)

  - A flaw was found in the way the Linux kernel's     networking subsystem handled offloaded packets with     multiple layers of encapsulation in the GRO (Generic     Receive Offload) code path. A remote attacker could use     this flaw to trigger unbounded recursion in the kernel     that could lead to stack corruption, resulting in a     system crash.(CVE-2016-8666)

  - A flaw was discovered in the Linux kernel's     implementation of VFIO. An attacker issuing an ioctl     can create a situation where memory is corrupted and     modify memory outside of the expected area. This may     overwrite kernel memory and subvert kernel     execution.(CVE-2016-9083)

  - The use of a kzalloc with an integer multiplication     allowed an integer overflow condition to be reached in     vfio_pci_intrs.c. This combined with CVE-2016-9083 may     allow an attacker to craft an attack and use     unallocated memory, potentially crashing the     machine.(CVE-2016-9084)

  - A flaw was found in the Linux kernel's implementation     of the SCTP protocol. A remote attacker could trigger     an out-of-bounds read with an offset of up to 64kB     potentially causing the system to crash.(CVE-2016-9555)

  - It was found that the blk_rq_map_user_iov() function in     the Linux kernel's block device implementation did not     properly restrict the type of iterator, which could     allow a local attacker to read or write to arbitrary     kernel memory locations or cause a denial of service     (use-after-free) by leveraging write access to a     /dev/sg device.(CVE-2016-9576)

  - Linux kernel built with the KVM visualization support     (CONFIG_KVM), with nested visualization(nVMX) feature     enabled(nested=1), is vulnerable to an uncaught     exception issue. It could occur if an L2 guest was to     throw an exception which is not handled by an L1     guest.(CVE-2016-9588)

  - It was discovered that root can gain direct access to     an internal keyring, such as '.dns_resolver' in RHEL-7     or '.builtin_trusted_keys' upstream, by joining it as     its session keyring. This allows root to bypass module     signature verification by adding a new public key of     its own devising to the keyring.(CVE-2016-9604)

  - A flaw was found in the Linux kernel's implementation     of XFS file attributes. Two memory leaks were detected     in xfs_attr_shortform_list and xfs_attr3_leaf_list_int     when running a docker container backed by xfs/overlay2.
    A dedicated attacker could possible exhaust all memory     and create a denial of service     situation.(CVE-2016-9685)

The SUSE Linux Enterprise 12 SP2 kernel was updated to 4.4.49 to receive various security and bugfixes. The following security bugs were fixed :

  - CVE-2016-7117: Use-after-free vulnerability in the
    __sys_recvmmsg function in net/socket.c in the Linux     kernel allowed remote attackers to execute arbitrary     code via vectors involving a recvmmsg system call that     was mishandled during error processing (bnc#1003077).

  - CVE-2017-5576: Integer overflow in the vc4_get_bcl     function in drivers/gpu/drm/vc4/vc4_gem.c in the     VideoCore DRM driver in the Linux kernel allowed local     users to cause a denial of service or possibly have     unspecified other impact via a crafted size value in a     VC4_SUBMIT_CL ioctl call (bnc#1021294).

  - CVE-2017-5577: The vc4_get_bcl function in     drivers/gpu/drm/vc4/vc4_gem.c in the VideoCore DRM     driver in the Linux kernel did not set an errno value     upon certain overflow detections, which allowed local     users to cause a denial of service (incorrect pointer     dereference and OOPS) via inconsistent size values in a     VC4_SUBMIT_CL ioctl call (bnc#1021294).

  - CVE-2017-5551: The simple_set_acl function in     fs/posix_acl.c in the Linux kernel preserved the setgid     bit during a setxattr call involving a tmpfs filesystem,     which allowed local users to gain group privileges by     leveraging the existence of a setgid program with     restrictions on execute permissions. (bnc#1021258).

  - CVE-2017-2583: The load_segment_descriptor     implementation in arch/x86/kvm/emulate.c in the Linux     kernel improperly emulated a 'MOV SS, NULL selector'     instruction, which allowed guest OS users to cause a     denial of service (guest OS crash) or gain guest OS     privileges via a crafted application (bnc#1020602).

  - CVE-2017-2584: arch/x86/kvm/emulate.c in the Linux     kernel allowed local users to obtain sensitive     information from kernel memory or cause a denial of     service (use-after-free) via a crafted application that     leverages instruction emulation for fxrstor, fxsave,     sgdt, and sidt (bnc#1019851).

  - CVE-2015-8709: kernel/ptrace.c in the Linux kernel     mishandled uid and gid mappings, which allowed local     users to gain privileges by establishing a user     namespace, waiting for a root process to enter that     namespace with an unsafe uid or gid, and then using the     ptrace system call. NOTE: the vendor states 'there is no     kernel bug here' (bnc#1010933).

  - CVE-2016-9806: Race condition in the netlink_dump     function in net/netlink/af_netlink.c in the Linux kernel     allowed local users to cause a denial of service (double     free) or possibly have unspecified other impact via a     crafted application that made sendmsg system calls,     leading to a free operation associated with a new dump     that started earlier than anticipated (bnc#1013540).

  - CVE-2017-5897: fixed a bug in the Linux kernel IPv6     implementation which allowed remote attackers to trigger     an out-of-bounds access, leading to a denial-of-service     attack (bnc#1023762).

  - CVE-2017-5970: Fixed a possible denial-of-service that     could have been triggered by sending bad IP options on a     socket (bsc#1024938).

  - CVE-2017-5986: an application could have triggered a     BUG_ON() in sctp_wait_for_sndbuf() if the socket TX     buffer was full, a thread was waiting on it to queue     more data, and meanwhile another thread peeled off the     association being used by the first thread     (bsc#1025235).

The update package also includes non-security fixes. See advisory for details.

This update for the Linux Kernel 3.12.55-52_42 fixes several issues.
The following security bugs were fixed :

  - CVE-2016-8655: A race condition in the af_packet     packet_set_ring function could be used by local     attackers to crash the kernel or gain privileges     (bsc#1012759).

  - CVE-2016-9555: The sctp_sf_ootb function in     net/sctp/sm_statefuns.c in the Linux kernel lacks     chunk-length checking for the first chunk, which allowed     remote attackers to cause a denial of service     (out-of-bounds slab access) or possibly have unspecified     other impact via crafted SCTP data (bsc#1012183).

  - CVE-2016-7117: Use-after-free vulnerability in the
    __sys_recvmmsg function in net/socket.c in the Linux     kernel allowed remote attackers to execute arbitrary     code via vectors involving a recvmmsg system call that     is mishandled during error processing (bsc#1003253).
