Tipo/Gravedad

Security Advisory: Important

Tema:

Updated libxml2 packages that fix a security issue are now available for
Red Hat Enterprise Linux 3, 4, and 5.

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

Descripción

The libxml2 packages provide a library that allows you to manipulate XML
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)

All users of libxml2 are advised to upgrade to these updated packages,
which contain a backported patch to resolve this issue.
