tag_insight = "libxslt is a library for transforming XML files into other XML files using
  the standard XSLT stylesheet transformation mechanism.

  A heap buffer overflow flaw was discovered in the RC4 libxslt library
  extension. An attacker could create a malicious XSL file that would cause a
  crash, or, possibly, execute arbitrary code with the privileges of the
  application using the libxslt library to perform XSL transformations on
  untrusted XSL style sheets. (CVE-2008-2935)
  
  Red Hat would like to thank Chris Evans for reporting this vulnerability.
  
  All libxslt users are advised to upgrade to these updated packages, which
  contain a backported patch to resolve this issue.";
