Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.04 / 13.10 : libxfont vulnerability (USN-2078-1)

high Nessus Plugin ID 71855

Language:

Synopsis

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

Description

It was discovered that libXfont incorrectly handled certain malformed BDF fonts. An attacker could use a specially crafted font file to cause libXfont to crash, or possibly execute arbitrary code in order to gain privileges. The default compiler options for affected releases should reduce the vulnerability 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.

Solution

Update the affected libxfont1 package.
