Ubuntu 6.06 LTS / 7.04 / 7.10 / 8.04 LTS : freetype vulnerabilities (USN-643-1)

High Nessus Plugin ID 37738


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


Multiple flaws were discovered in the PFB and TTF font handling code in freetype. If a user were tricked into using a specially crafted font file, a remote attacker could execute arbitrary code with user privileges or cause the application linked against freetype to crash, leading to a denial of service.

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.
