CVEs (cve.mitre.org):	CVE-2008-2935

Details

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.

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
