Ubuntu 8.04 LTS / 10.04 LTS / 10.10 / 11.04 : libxml2 vulnerability (USN-1153-1)

high Nessus Plugin ID 55168
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

Chris Evans discovered that libxml2 incorrectly handled memory allocation. If an application using libxml2 opened a specially crafted XML file, an attacker could cause a denial of service or possibly execute code as the user invoking the program.

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.
