Ubuntu Security Notice USN-1209-2
September 19, 2011

libav vulnerabilities
==========================================================================

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

- Ubuntu 11.04

Summary:

Libav could be made to 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 ogg
files. If a user were tricked into opening a crafted ogg 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.
(CVE-2011-1196)

It was discovered that Libav incorrectly handled certain malformed AMV
files. If a user were tricked into opening a crafted AMV 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.
(CVE-2011-1931)

Emmanouel Kellinis discovered that Libav incorrectly handled certain
malformed CAVS files. If a user were tricked into opening a crafted CAVS
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. (CVE-2011-3362)

Update instructions:

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

Ubuntu 11.04:
  libavcodec52                    4:0.6.2-1ubuntu1.1
  libavformat52                   4:0.6.2-1ubuntu1.1

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