RHEL 2.1 / 3 : libxml2 (RHSA-2004:090)

high Nessus Plugin ID 12474

Synopsis

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

Description

Updated libxml2 packages that fix an overflow when parsing remote resources are now available.

libxml2 is a library for manipulating XML files.

Yuuichi Teranishi discovered a flaw in libxml2 versions prior to 2.6.6. When fetching a remote resource via FTP or HTTP, libxml2 uses special parsing routines. These routines can overflow a buffer if passed a very long URL. If an attacker is able to find an application using libxml2 that parses remote resources and allows them to influence the URL, then this flaw could be used to execute arbitrary code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2004-0110 to this issue.

All users are advised to upgrade to these updated packages, which contain a backported fix and are not vulnerable to this issue.

Solution

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