Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2009-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

It was discovered that libxml2 did not correctly handle long entity
names. If a user were tricked into processing a specially crafted XML
document, a remote attacker could execute arbitrary code with user
privileges or cause the application linked against libxml2 to crash,
leading to a denial of service. (CVE-2008-3529)

USN-640-1 fixed vulnerabilities in libxml2. When processing extremely
large XML documents with valid entities, it was possible to
incorrectly trigger the newly added vulnerability protections. This
update fixes the problem. (CVE-2008-3281).

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
