  support for reading, modifying, and writing XML and HTML files.

  An integer overflow flaw causing a heap-based buffer overflow was found in
  the libxml2 XML parser. If an application linked against libxml2 processed
  untrusted, malformed XML content, it could cause the application to crash
  or, possibly, execute arbitrary code. (CVE-2008-4226)
  
  A denial of service flaw was discovered in the libxml2 XML parser. If an
  application linked against libxml2 processed untrusted, malformed XML
  content, it could cause the application to enter an infinite loop.
  (CVE-2008-4225)
  
  Red Hat would like to thank Drew Yao of the Apple Product Security team for
  reporting these issues.
  
  Users of libxml2 are advised to upgrade to these updated packages, which
  contain backported patches to correct these issues.";
