libxml2 security update

CentOS Errata and Security Advisory CESA-2008:0032

The libxml2 packages provide a library that allows you to manipulate XML
files. It includes support to read, modify, and write XML and HTML files.

A denial of service flaw was found in the way libxml2 processes certain
content. If an application linked against libxml2 processes malformed XML
content, it could cause the application to stop responding. (CVE-2007-6284)

Red Hat would like to thank the Google Security Team for responsibly
disclosing this issue.

All users are advised to upgrade to these updated packages, which contain a
backported patch to resolve this issue.
