USN-931-2: FFmpeg regression

26 April 2010

FFmpeg regression




USN-931-1 fixed vulnerabilities in FFmpeg. The update introduced a
regression when trying to play certain multimedia files. This update fixes
the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that FFmpeg contained multiple security issues when
handling certain multimedia files. If a user were tricked into opening a
crafted multimedia 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 9.10
Ubuntu 9.04
Ubuntu 8.10
Ubuntu 8.04

In general, a standard system upgrade is sufficient to effect the
necessary changes.
