Ubuntu 8.04 LTS / 10.04 LTS / 11.10 / 12.04 LTS / 12.10 : libxml2 vulnerability (USN-1656-1)

medium Nessus Plugin ID 63165

Language:

Synopsis

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

Description

It was discovered that libxml2 had a heap-based buffer underflow when parsing entities. If a user or automated system were tricked into processing a specially crafted XML document, applications linked against libxml2 could be made to crash or possibly execute arbitrary code.

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 libxml2 package.
