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

critical Nessus Plugin ID 34811

Synopsis

The remote Red Hat host is missing one or more security updates for libxml2.

Description

The remote Redhat Enterprise Linux 4 / 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2008:0988 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL libxml2 package based on the guidance in RHSA-2008:0988.
