Mesa Vulnerabilities Fixed in Ubuntu 13.04

A couple of other distributions from Canonical have been affected

On June 20, Canonical published details about Mesa vulnerabilities for its Ubuntu 13.04, Ubuntu 12.10, and Ubuntu 12.04 LTS operating systems.

According to Canonical, Mesa could have been made to crash or to run programs, as the user’s login, if it received specially crafted input.

It has been discovered that Mesa incorrectly handled certain memory calculations. An attacker could use this flaw to cause an application to crash, or possibly execute arbitrary code.

For a more detailed description of the security problems, you can visit Canonical's security notification.

Users can simply fix the security flaws by upgrading the operating systems to the latest python-swift package, specific to each distribution.

A normal system update, executed with the Update Manager, will implement all the necessary changes. A complete restart is necessary.
