=========================================================================Ubuntu Security Notice USN-3034-1
July 14, 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 under certain conditions.

Software Description:
- linux: Linux kernel

Details:

Jan Stancek discovered that the Linux kernel's memory manager did not
properly handle moving pages mapped by the asynchronous I/O (AIO) ring
buffer to the other nodes. A local attacker could use this to cause a
denial of service (system crash).

Update instructions:

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

Ubuntu 14.04 LTS:
  linux-image-3.13.0-92-generic   3.13.0-92.139
  linux-image-3.13.0-92-generic-lpae  3.13.0-92.139
  linux-image-3.13.0-92-lowlatency  3.13.0-92.139
  linux-image-3.13.0-92-powerpc-e500  3.13.0-92.139
  linux-image-3.13.0-92-powerpc-e500mc  3.13.0-92.139
  linux-image-3.13.0-92-powerpc-smp  3.13.0-92.139
  linux-image-3.13.0-92-powerpc64-emb  3.13.0-92.139
  linux-image-3.13.0-92-powerpc64-smp  3.13.0-92.139

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.
