Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

Ilja van Sprundel discovered that libXfont incorrectly handled font metadata file parsing. A local attacker could use this issue to cause libXfont to crash, or possibly execute arbitrary code in order to gain privileges. (CVE-2014-0209)

Ilja van Sprundel discovered that libXfont incorrectly handled X Font Server replies. A malicious font server could return specially crafted data that could cause libXfont to crash, or possibly execute arbitrary code. This issue only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS, Ubuntu 12.10 and Ubuntu 13.10. (CVE-2014-0210, CVE-2014-0211).

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 libxfont-dev, libxfont1 and / or libxfont1-udeb packages.
