RHEL 2.1 / 3 / 4 / 5 : libxml2 (RHSA-2008:0988)

Critical Nessus Plugin ID 34811

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated libxml2 packages that fix security issues are now available for Red Hat Enterprise Linux 2.1, 3, 4, and 5.

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

libxml2 is a library for parsing and manipulating XML files. It includes support for reading, modifying, and writing XML and HTML files.

An integer overflow flaw causing a heap-based buffer overflow was found in the libxml2 XML parser. If an application linked against libxml2 processed untrusted, malformed XML content, it could cause the application to crash or, possibly, execute arbitrary code.
(CVE-2008-4226)

A denial of service flaw was discovered in the libxml2 XML parser. If an application linked against libxml2 processed untrusted, malformed XML content, it could cause the application to enter an infinite loop.
(CVE-2008-4225)

Red Hat would like to thank Drew Yao of the Apple Product Security team for reporting these issues.

Users of libxml2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

Solution

Update the affected libxml2, libxml2-devel and / or libxml2-python packages.
