3. Description:

 

The libxml2 library is a development toolbox providing the implementation

of various XML standards.

 

A denial of service flaw was found in the way libxml2 performed string

substitutions when entity values for entity references replacement was

enabled. A remote attacker could provide a specially-crafted XML file that,

when processed by an application linked against libxml2, would lead to

excessive CPU consumption. (CVE-2013-0338)

 

All users of libxml2 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

https://access.redhat.com/knowledge/articles/11258

 

5. Bugs fixed (http://bugzilla.redhat.com/):

 

912400 - CVE-2013-0338 libxml2: CPU consumption DoS when performing string substitutions during entities expansion
