Ubuntu 12.04 LTS / 14.04 LTS / 16.04 LTS : fontconfig vulnerability (USN-3063-1)

Medium Nessus Plugin ID 93025


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


Tobias Stoeckmann discovered that Fontconfig incorrectly handled cache files. A local attacker could possibly use this issue with a specially crafted cache file to elevate 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 fontconfig and / or libfontconfig1 packages.
