Description

From Red Hat Security Advisory 2008:0032 :

Updated libxml2 packages that fix a security issue are now available.

This update has been rated as having important security impact by the Red Hat Security Response Team.

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.
