The remote Oracle Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2016-3651 advisory.

  - The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through 4.8.11 does not ensure that memory     is allocated for limb data, which allows local users to cause a denial of service (stack memory corruption     and panic) via an add_key system call for an RSA key with a zero exponent. (CVE-2016-8650)

  - The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel before 4.8.8 lacks chunk-length     checking for the first chunk, which allows remote attackers to cause a denial of service (out-of-bounds     slab access) or possibly have unspecified other impact via crafted SCTP data. (CVE-2016-9555)

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

Security Fix(es) :

  - 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, Important)

  - A use-after-free vulnerability was found in     tcp_xmit_retransmit_queue and other tcp_* functions.
    This condition could allow an attacker to send an     incorrect selective acknowledgment to existing     connections, possibly resetting a connection.
    (CVE-2016-6828, Moderate)

  - 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,     Moderate)

Bug Fix(es) :

  - Previously, the performance of Internet Protocol over     InfiniBand (IPoIB) was suboptimal due to a conflict of     IPoIB with the Generic Receive Offload (GRO)     infrastructure. With this update, the data cached by the     IPoIB driver has been moved from a control block into     the IPoIB hard header, thus avoiding the GRO problem and     the corruption of IPoIB address information. As a     result, the performance of IPoIB has been improved.

  - Previously, when a virtual machine (VM) with     PCI-Passthrough interfaces was recreated, a race     condition between the eventfd daemon and the virqfd     daemon occurred. Consequently, the operating system     rebooted. This update fixes the race condition. As a     result, the operating system no longer reboots in the     described situation.

  - Previously, a packet loss occurred when the team driver     in round-robin mode was sending a large number of     packets. This update fixes counting of the packets in     the round-robin runner of the team driver, and the     packet loss no longer occurs in the described situation.

  - Previously, the virtual network devices contained in the     deleted namespace could be deleted in any order. If the     loopback device was not deleted as the last item, other     netns devices, such as vxlan devices, could end up with     dangling references to the loopback device.
    Consequently, deleting a network namespace (netns)     occasionally ended by a kernel oops. With this update,     the underlying source code has been fixed to ensure the     correct order when deleting the virtual network devices     on netns deletion. As a result, the kernel oops no     longer occurs under the described circumstances.

  - Previously, a Kabylake system with a Sunrise Point     Platform Controller Hub (PCH) with a PCI device ID of     0xA149 showed the following warning messages during the     boot :

'Unknown Intel PCH (0xa149) detected.' 'Warning: Intel Kabylake processor with unknown PCH - this hardware has not undergone testing ...'

The messages were shown because this PCH was not properly recognized.
With this update, the problem has been fixed, and the operating system now boots without displaying the warning messages.

  - Previously, the operating system occasionally became     unresponsive after a long run. This was caused by a race     condition between the try_to_wake_up() function and a     woken up task in the core scheduler. With this update,     the race condition has been fixed, and the operating     system no longer locks up in the described scenario.

Andrey Konovalov discovered that the SCTP implementation in the Linux kernel improperly handled validation of incoming data. A remote attacker could use this to cause a denial of service (system crash).
(CVE-2016-9555)

It was discovered that multiple memory leaks existed in the XFS implementation in the Linux kernel. A local attacker could use this to cause a denial of service (memory consumption). (CVE-2016-9685).

  - CVE-2016-3841: The IPv6 stack in the Linux kernel     mishandled options data, which allowed local users to     gain privileges or cause a denial of service     (use-after-free and system crash) via a crafted sendmsg     system call (bnc#992566).

  - CVE-2016-9685: Multiple memory leaks in error paths in     fs/xfs/xfs_attr_list.c in the Linux kernel allowed local     users to cause a denial of service (memory consumption)     via crafted XFS filesystem operations (bnc#1012832).

  - CVE-2015-1350: The VFS subsystem in the Linux kernel 3.x     provides an incomplete set of requirements for setattr     operations that underspecified removing extended     privilege attributes, which allowed local users to cause     a denial of service (capability stripping) via a failed     invocation of a system call, as demonstrated by using     chown to remove a capability from the ping or Wireshark     dumpcap program (bnc#914939).

  - CVE-2016-7911: Race condition in the get_task_ioprio     function in block/ioprio.c in the Linux kernel allowed     local users to gain privileges or cause a denial of     service (use-after-free) via a crafted ioprio_get system     call (bnc#1010711).
