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. (CVE-2015-5312, CVE-2015-7497,
CVE-2015-7498, CVE-2015-7499, CVE-2015-7500 CVE-2015-7941, CVE-2015-7942,
CVE-2015-8241, CVE-2015-8242, CVE-2015-8317, BZ#1213957, BZ#1281955)

Red Hat would like to thank the GNOME project for reporting CVE-2015-7497,
CVE-2015-7498, CVE-2015-7499, CVE-2015-7500, CVE-2015-8241, CVE-2015-8242,
and CVE-2015-8317. Upstream acknowledges Kostya Serebryany of Google as the
original reporter of CVE-2015-7497, CVE-2015-7498, CVE-2015-7499, and
CVE-2015-7500; Hugh Davenport as the original reporter of CVE-2015-8241 and
CVE-2015-8242; and Hanno Boeck as the original reporter of CVE-2015-8317.

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