Ubuntu 10.04 LTS / 10.10 / 11.04 : libxfont vulnerability (USN-1191-1)

high Nessus Plugin ID 55858

Synopsis

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

Description

Tomas Hoger discovered that libXfont incorrectly handled certain malformed compressed 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.

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.
