Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS / 14.10 : libxfont vulnerabilities (USN-2536-1)

High Nessus Plugin ID 81951

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

Ilja van Sprundel, Alan Coopersmith, and William Robinet discovered that libXfont incorrectly handled malformed bdf fonts. A local attacker could use this issue to cause libXfont to crash, or possibly execute arbitrary code in order to gain 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.

Solution

Update the affected libxfont1 package.
