Ubuntu Security Notice USN-1929-1
August 20, 2013

linux vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

The system could be made to expose sensitive information.

Software Description:
- linux: Linux kernel

Details:

An information leak was discovered in the Linux kernel's fanotify
interface. A local user could exploit this flaw to obtain sensitive
information from kernel memory.

Update instructions:

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

Ubuntu 12.04 LTS:
  linux-image-3.2.0-52-generic    3.2.0-52.78
  linux-image-3.2.0-52-generic-pae  3.2.0-52.78
  linux-image-3.2.0-52-highbank   3.2.0-52.78
  linux-image-3.2.0-52-omap       3.2.0-52.78
  linux-image-3.2.0-52-powerpc-smp  3.2.0-52.78
  linux-image-3.2.0-52-powerpc64-smp  3.2.0-52.78
  linux-image-3.2.0-52-virtual    3.2.0-52.78

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. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
