3. Description:

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-2008-3281)

Red Hat would like to thank Andreas Solberg for responsibly disclosing this
issue.

All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to resolve this issue.

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network.  Details on how to use
the Red Hat Network to apply this update are available at
