3. Description:
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.
4. 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
the Red Hat Network to apply this update are available at
