USN-1790-1: Libav vulnerabilities Ubuntu Security Notice USN-1790-1
4th April, 2013 libav vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Ubuntu 12.10 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
version:
Ubuntu 12.10:
libavformat53 6:0.8.6-0ubuntu0.12.10.1
libavcodec53 6:0.8.6-0ubuntu0.12.10.1
Ubuntu 12.04 LTS:
libavformat53 4:0.8.6-0ubuntu0.12.04.1
libavcodec53 4:0.8.6-0ubuntu0.12.04.1
To update your system, please follow these instructions:
https://wiki.ubuntu.com/Security/Upgrades.
This update uses a new upstream release, which includes additional bug fixes.
In general, a standard system update will make all the necessary changes.
