libav vulnerabilities
==========================================================================
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 6:0.8.13-0ubuntu0.13.10.1
libavformat53 6:0.8.13-0ubuntu0.13.10.1
Ubuntu 12.04 LTS:
libavcodec53 4:0.8.13-0ubuntu0.12.04.1
libavformat53 4:0.8.13-0ubuntu0.12.04.1
This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
