"From Red Hat Security Advisory 2008:0649 :

Updated libxslt packages that fix a security issue are now available
for Red Hat Enterprise Linux 4 and Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

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."
