Ubuntu Security Notice USN-3445-1
October 10, 2017

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

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

- - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- - linux: Linux kernel

Details:

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)

Andrey Konovalov discovered that a divide-by-zero error existed in the TCP
stack implementation in the Linux kernel. A local attacker could use this
to cause a denial of service (system crash). (CVE-2017-14106)

Update instructions:

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-133-generic  3.13.0-133.182
  linux-image-3.13.0-133-generic-lpae  3.13.0-133.182
  linux-image-3.13.0-133-lowlatency  3.13.0-133.182
  linux-image-3.13.0-133-powerpc-e500  3.13.0-133.182
  linux-image-3.13.0-133-powerpc-e500mc  3.13.0-133.182
  linux-image-3.13.0-133-powerpc-smp  3.13.0-133.182
  linux-image-3.13.0-133-powerpc64-emb  3.13.0-133.182
  linux-image-3.13.0-133-powerpc64-smp  3.13.0-133.182
  linux-image-generic             3.13.0.133.142
  linux-image-generic-lpae        3.13.0.133.142
  linux-image-lowlatency          3.13.0.133.142
  linux-image-powerpc-e500        3.13.0.133.142
  linux-image-powerpc-e500mc      3.13.0.133.142
  linux-image-powerpc-smp         3.13.0.133.142
  linux-image-powerpc64-emb       3.13.0.133.142
  linux-image-powerpc64-smp       3.13.0.133.142

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.
