Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.


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.

Risk factor :
