How to fix?

Upgrade Centos:6 libxml2-python to version 0:2.7.6-4.el6 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxml2-python package and not the libxml2-python package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

libxml2 before 2.7.8, as used in Google Chrome before 7.0.517.44, Apple Safari 5.0.2 and earlier, and other products, reads from invalid memory locations during processing of malformed XPath expressions, which allows context-dependent attackers to cause a denial of service (application crash) via a crafted XML document.
