Red Hat: Updated libxml2 packages fix a security issue

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. Fixed packages are available from updates.redhat.com.
