=====================================================================

 

1. Summary:

 

Updated libxml2 packages that fix one security issue are now available for

Red Hat Enterprise Linux 5.

 

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.

 

2. Relevant releases/architectures:

 

RHEL Desktop Workstation (v. 5 client) - i386, x86_64

Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

 

3. Description:

 

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.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to use the

Red Hat Network to apply this update are available at
