Ubuntu Security Notice USN-3161-1
December 20, 2016

linux vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

Tilman Schmidt and Sasha Levin discovered a use-after-free condition in the
TTY implementation in the Linux kernel. A local attacker could use this to
expose sensitive information (kernel memory). (CVE-2015-8964)

It was discovered that the Video For Linux Two (v4l2) implementation in the
Linux kernel did not properly handle multiple planes when processing a
VIDIOC_DQBUF ioctl(). A local attacker could use this to cause a denial of
service (system crash) or possibly execute arbitrary code. (CVE-2016-4568)

CAI Qian discovered that shared bind mounts in a mount namespace
exponentially added entries without restriction to the Linux kernel's mount
table. A local attacker could use this to cause a denial of service (system
crash). (CVE-2016-6213)

It was discovered that the KVM implementation for x86/x86_64 in the Linux
kernel could dereference a null pointer. An attacker in a guest virtual
machine could use this to cause a denial of service (system crash) in the
KVM host. (CVE-2016-8630)

Eyal Itkin discovered that the IP over IEEE 1394 (FireWire) implementation
in the Linux kernel contained a buffer overflow when handling fragmented
packets. A remote attacker could use this to possibly execute arbitrary
code with administrative privileges. (CVE-2016-8633)

Marco Grassi discovered that the TCP implementation in the Linux kernel
mishandles socket buffer (skb) truncation. A local attacker could use this
to cause a denial of service (system crash). (CVE-2016-8645)

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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 16.04 LTS:
linux-image-4.4.0-57-generic 4.4.0-57.78
linux-image-4.4.0-57-generic-lpae 4.4.0-57.78
linux-image-4.4.0-57-lowlatency 4.4.0-57.78
linux-image-4.4.0-57-powerpc-e500mc 4.4.0-57.78
linux-image-4.4.0-57-powerpc-smp 4.4.0-57.78
linux-image-4.4.0-57-powerpc64-emb 4.4.0-57.78
linux-image-4.4.0-57-powerpc64-smp 4.4.0-57.78
linux-image-generic 4.4.0.57.60
linux-image-generic-lpae 4.4.0.57.60
linux-image-lowlatency 4.4.0.57.60
linux-image-powerpc-e500mc 4.4.0.57.60
linux-image-powerpc-smp 4.4.0.57.60
linux-image-powerpc64-emb 4.4.0.57.60
linux-image-powerpc64-smp 4.4.0.57.60

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
