Ubuntu Security Notice USN-2787-1
October 28, 2015

audiofile vulnerability
==========================================================================

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

- Ubuntu 15.10
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

audiofile could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- audiofile: Open-source version of the SGI audiofile library

Details:

Fabrizio Gennari discovered that audiofile incorrectly handled changing
both the sample format and the number of channels. If a user or automated
system were tricked into processing a specially crafted file, audiofile
could be made to crash, leading to a denial of service, or possibly execute
arbitrary code.

Update instructions:

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

Ubuntu 15.10:
  libaudiofile1                   0.3.6-2ubuntu0.15.10.1

Ubuntu 15.04:
  libaudiofile1                   0.3.6-2ubuntu0.15.04.1

Ubuntu 14.04 LTS:
  libaudiofile1                   0.3.6-2ubuntu0.14.04.1

Ubuntu 12.04 LTS:
  libaudiofile1                   0.3.3-2ubuntu0.1

In general, a standard system update will make all the necessary changes.
