Detail

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

- Ubuntu 13.10 - Ubuntu 12.04 LTS

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 13.10:
libavcodec53 6:0.8.12-0ubuntu0.13.10.1
libavformat53 6:0.8.12-0ubuntu0.13.10.1

Ubuntu 12.04 LTS:
libavcodec53 4:0.8.12-0ubuntu0.12.04.1
libavformat53 4:0.8.12-0ubuntu0.12.04.1

This update uses a new upstream release, which includes additional bug fixes. In general, a standard system update will make all the necessary changes.
