Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated libxml2 packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The libxml2 library is a development toolbox providing the implementation of various XML standards.

Several denial of service flaws were found in libxml2, a library providing support for reading, modifying, and writing XML and HTML files. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or in certain cases crash the application.
