============================================================================

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

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10

Summary:

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

Software Description:
- libav: Multimedia player, server, encoder and transcoder

Details:

It was discovered that Libav incorrectly handled certain malformed media
files. If a user were tricked into opening a crafted media file, an
attacker could cause a denial of service via application crash, or possibly
execute arbitrary code with the privileges of the user invoking the
program.

Update instructions:

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

Ubuntu 12.10:
libavcodec53 6:0.8.5-0ubuntu0.12.10.1
