  files. It includes support to read, modify, and write XML and HTML files.

  A heap-based buffer overflow flaw was found in the way libxml2 handled long
  XML entity names. If an application linked against libxml2 processed
  untrusted malformed XML content, it could cause the application to crash
  or, possibly, execute arbitrary code. (CVE-2008-3529)
  
  A denial of service flaw was found in the way libxml2 processed certain
  content. If an application linked against libxml2 processed malformed XML
  content, it could cause the application to use an excessive amount of CPU
  time and memory, and stop responding. (CVE-2003-1564)
  
  All users of libxml2 are advised to upgrade to these updated packages,
  which contain backported patches to resolve these issues.";
