Ubuntu 6.06 LTS / 8.04 LTS / 8.10 / 9.04 : freetype vulnerability (USN-767-1)

Critical Nessus Plugin ID 38196


The remote Ubuntu host is missing one or more security-related patches.


Tavis Ormandy discovered that FreeType did not correctly handle certain large values in font files. If a user were tricked into using a specially crafted font file, a remote attacker could execute arbitrary code with user privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected freetype2-demos, libfreetype6 and / or libfreetype6-dev packages.
