=========================================================================Ubuntu Security Notice USN-2975-1
May 16, 2016

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

- Ubuntu 14.04 LTS

Summary:

The system could be made to crash or run programs as an administrator.

Software Description:
- linux: Linux kernel

Details:

Philip Pettersson discovered that the Linux kernel's ASN.1 DER decoder did
not properly process certificate files with tags of indefinite length. A
local unprivileged attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code with administrative
privileges. (CVE-2016-0758)

Update instructions:

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-86-generic   3.13.0-86.131
  linux-image-3.13.0-86-generic-lpae  3.13.0-86.131
  linux-image-3.13.0-86-lowlatency  3.13.0-86.131
  linux-image-3.13.0-86-powerpc-e500  3.13.0-86.131
  linux-image-3.13.0-86-powerpc-e500mc  3.13.0-86.131
  linux-image-3.13.0-86-powerpc-smp  3.13.0-86.131
  linux-image-3.13.0-86-powerpc64-emb  3.13.0-86.131
  linux-image-3.13.0-86-powerpc64-smp  3.13.0-86.131

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.
