Details

It was discovered that the QT demuxer in xine-lib did not correctly handle
a large count value in an STTS atom, resulting in a heap-based buffer
overflow. If a user or automated system were tricked into opening a
specially crafted MOV file, an attacker could execute arbitrary code as the
user invoking the program. (CVE-2009-1274)

USN-746-1 provided updated xine-lib packages to fix multiple security
vulnerabilities. The security patch to fix CVE-2009-0698 was incomplete.
This update corrects the problem.

Original advisory details:
It was discovered that the 4xm demuxer in xine-lib did not correctly
handle a large current_track value in a 4xm file, resulting in an integer
overflow. If a user or automated system were tricked into opening a
specially crafted 4xm movie file, an attacker could crash xine-lib or
possibly execute arbitrary code with the privileges of the user invoking
the program. (CVE-2009-0698)

Update instructions

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

Ubuntu 8.10
Ubuntu 8.04
Ubuntu 6.06

After a standard system upgrade you need to restart applications linked
against xine-lib, such as Totem-xine and Amarok, to effect the necessary
changes.
