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.

A security issue affects these releases of Ubuntu and its derivatives:
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)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
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.
