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

  - The cgroup offline implementation in the Linux kernel through 4.8.11 mishandles certain drain operations,     which allows local users to cause a denial of service (system hang) by leveraging access to a container     environment for executing a crafted application, as demonstrated by trinity. (CVE-2016-9191)

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

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

  - CVE-2016-6786 / CVE-2016-6787     It was discovered that the performance events subsystem     does not properly manage locks during certain     migrations, allowing a local attacker to escalate     privileges. This can be mitigated by disabling     unprivileged use of performance events:sysctl     kernel.perf_event_paranoid=3

  - CVE-2016-8405     Peter Pi of Trend Micro discovered that the frame buffer     video subsystem does not properly check bounds while     copying color maps to userspace, causing a heap buffer     out-of-bounds read, leading to information disclosure.

  - CVE-2016-9191     CAI Qian discovered that reference counting is not     properly handled within proc_sys_readdir in the sysctl     implementation, allowing a local denial of service     (system hang) or possibly privilege escalation.

  - CVE-2017-2583     Xiaohan Zhang reported that KVM for amd64 does not     correctly emulate loading of a null stack selector. This     can be used by a user in a guest VM for denial of     service (on an Intel CPU) or to escalate privileges     within the VM (on an AMD CPU).

  - CVE-2017-2584     Dmitry Vyukov reported that KVM for x86 does not     correctly emulate memory access by the SGDT and SIDT     instructions, which can result in a use-after-free and     information leak.

  - CVE-2017-2596     Dmitry Vyukov reported that KVM leaks page references     when emulating a VMON for a nested hypervisor. This can     be used by a privileged user in a guest VM for denial of     service or possibly to gain privileges in the host.

  - CVE-2017-2618     It was discovered that an off-by-one in the handling of     SELinux attributes in /proc/pid/attr could result in     local denial of service.

  - CVE-2017-5549     It was discovered that the KLSI KL5KUSB105 serial USB     device driver could log the contents of uninitialised     kernel memory, resulting in an information leak.

  - CVE-2017-5551     Jan Kara found that changing the POSIX ACL of a file on     tmpfs never cleared its set-group-ID flag, which should     be done if the user changing it is not a member of the     group-owner. In some cases, this would allow the     user-owner of an executable to gain the privileges of     the group-owner.

  - CVE-2017-5897     Andrey Konovalov discovered an out-of-bounds read flaw     in the ip6gre_err function in the IPv6 networking code.

  - CVE-2017-5970     Andrey Konovalov discovered a denial-of-service flaw in     the IPv4 networking code. This can be triggered by a     local or remote attacker if a local UDP or raw socket     has the IP_RETOPTS option enabled.

  - CVE-2017-6001     Di Shen discovered a race condition between concurrent     calls to the performance events subsystem, allowing a     local attacker to escalate privileges. This flaw exists     because of an incomplete fix of CVE-2016-6786. This can     be mitigated by disabling unprivileged use of     performance events: sysctl kernel.perf_event_paranoid=3

  - CVE-2017-6074     Andrey Konovalov discovered a use-after-free     vulnerability in the DCCP networking code, which could     result in denial of service or local 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-2017-7308: The packet_set_ring function in     net/packet/af_packet.c in the Linux kernel did not     properly validate certain block-size data, which allowed     local users to cause a denial of service (overflow) or     possibly have unspecified other impact via crafted     system calls (bnc#1031579)

  - CVE-2017-2671: The ping_unhash function in     net/ipv4/ping.c in the Linux kernel was too late in     obtaining a certain lock and consequently could not     ensure that disconnect function calls are safe, which     allowed local users to cause a denial of service (panic)     by leveraging access to the protocol value of     IPPROTO_ICMP in a socket system call (bnc#1031003)

  - CVE-2017-7294: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not validate addition of certain levels data,     which allowed local users to trigger an integer overflow     and out-of-bounds write, and cause a denial of service     (system hang or crash) or possibly gain privileges, via     a crafted ioctl call for a /dev/dri/renderD* device     (bnc#1031440)

  - CVE-2017-7261: The vmw_surface_define_ioctl function in     drivers/gpu/drm/vmwgfx/vmwgfx_surface.c in the Linux     kernel did not check for a zero value of certain levels     data, which allowed local users to cause a denial of     service (ZERO_SIZE_PTR dereference, and GPF and possibly     panic) via a crafted ioctl call for a /dev/dri/renderD*     device (bnc#1031052)

  - CVE-2017-7187: The sg_ioctl function in     drivers/scsi/sg.c in the Linux kernel allowed local     users to cause a denial of service (stack-based buffer     overflow) or possibly have unspecified other impact via     a large command size in an SG_NEXT_CMD_LEN ioctl call,     leading to out-of-bounds write access in the sg_write     function (bnc#1030213)

  - CVE-2016-9588: arch/x86/kvm/vmx.c in the Linux kernel     mismanaged the #BP and #OF exceptions, which allowed     guest OS users to cause a denial of service (guest OS     crash) by declining to handle an exception thrown by an     L2 guest (bsc#1015703).

  - CVE-2017-5669: The do_shmat function in ipc/shm.c in the     Linux kernel did not restrict the address calculated by     a certain rounding operation, which allowed local users     to map page zero, and consequently bypass a protection     mechanism that exists for the mmap system call, by     making crafted shmget and shmat system calls in a     privileged context (bnc#1026914).

  - CVE-2016-10200: Race condition in the L2TPv3 IP     Encapsulation feature in the Linux kernel allowed local     users to gain privileges or cause a denial of service     (use-after-free) by making multiple bind system calls     without properly ascertaining whether a socket has the     SOCK_ZAPPED status, related to net/l2tp/l2tp_ip.c and     net/l2tp/l2tp_ip6.c (bnc#1028415)

  - CVE-2016-10208: The ext4_fill_super function in     fs/ext4/super.c in the Linux kernel did not properly     validate meta block groups, which allowed physically     proximate attackers to cause a denial of service     (out-of-bounds read and system crash) via a crafted ext4     image (bnc#1023377).

  - CVE-2017-5897: The ip6gre_err function in     net/ipv6/ip6_gre.c in the Linux kernel allowed remote     attackers to have unspecified impact via vectors     involving GRE flags in an IPv6 packet, which trigger an     out-of-bounds access (bsc#1023762).

  - CVE-2017-5986: A race condition in the     sctp_wait_for_sndbuf function in net/sctp/socket.c in     the Linux kernel allowed local users to cause a denial     of service (assertion failure and panic) via a     multithreaded application that peels off an association     in a certain buffer-full state (bsc#1025235).

  - CVE-2017-6074: The dccp_rcv_state_process function in     net/dccp/input.c in the Linux kernel mishandled     DCCP_PKT_REQUEST packet data structures in the LISTEN     state, which allowed local users to obtain root     privileges or cause a denial of service (double free)     via an application that made an IPV6_RECVPKTINFO     setsockopt system call (bnc#1026024)

  - CVE-2016-9191: The cgroup offline implementation in the     Linux kernel mishandled certain drain operations, which     allowed local users to cause a denial of service (system     hang) by leveraging access to a container environment     for executing a crafted application (bnc#1008842)

  - CVE-2017-6348: The hashbin_delete function in     net/irda/irqueue.c in the Linux kernel improperly     managed lock dropping, which allowed local users to     cause a denial of service (deadlock) via crafted     operations on IrDA devices (bnc#1027178).

  - CVE-2016-10044: The aio_mount function in fs/aio.c in     the Linux kernel did not properly restrict execute     access, which made it easier for local users to bypass     intended SELinux W^X policy restrictions, and     consequently gain privileges, via an io_setup system     call (bnc#1023992).

  - CVE-2016-3070: The trace_writeback_dirty_page     implementation in include/trace/events/writeback.h in     the Linux kernel improperly interacts with mm/migrate.c,     which allowed local users to cause a denial of service     (NULL pointer dereference and system crash) or possibly     have unspecified other impact by triggering a certain     page move (bnc#979215).

  - CVE-2016-5243: The tipc_nl_compat_link_dump function in     net/tipc/netlink_compat.c in the Linux kernel did not     properly copy a certain string, which allowed local     users to obtain sensitive information from kernel stack     memory by reading a Netlink message (bnc#983212).

  - CVE-2017-6345: The LLC subsystem in the Linux kernel did     not ensure that a certain destructor exists in required     circumstances, which allowed local users to cause a     denial of service (BUG_ON) or possibly have unspecified     other impact via crafted system calls (bnc#1027190)
