Ubuntu Security Notice USN-1675-1
December 19, 2012

ffmpeg vulnerabilities
==========================================================================

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

- Ubuntu 10.04 LTS

Summary:

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

Software Description:
- ffmpeg: multimedia player, server and encoder

Details:

It was discovered that FFmpeg 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 10.04 LTS:
libavcodec52 4:0.5.9-0ubuntu0.10.04.2
libavformat52 4:0.5.9-0ubuntu0.10.04.2

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