Synopsis :

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

Description :

Updated libxml2 packages that fix one security issue are now available
for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

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

A denial of service flaw was found in libxml2, a library providing
support to read, modify and write XML and HTML files. A remote
attacker could provide a specially crafted XML file that, when
processed by an application using libxml2, would lead to excessive CPU
consumption (denial of service) based on excessive entity
substitutions, even if entity substitution was disabled, which is the
parser default behavior. (CVE-2014-3660)

All libxml2 users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. The desktop
must be restarted (log out, then log back in) for this update to take
effect.
