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

medium Nessus Plugin ID 63165
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
