3. Description:

 

The libxml2 library is a development toolbox providing the implementation

of various XML standards.

 

A heap-based buffer underflow flaw was found in the way libxml2 decoded

certain entities. A remote attacker could provide a specially-crafted XML

file that, when opened in an application linked against libxml2, would

cause the application to crash or, potentially, execute arbitrary code with

the privileges of the user running the application. (CVE-2012-5134)

 

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/):

 

880466 - CVE-2012-5134 libxml2: Heap-buffer-underflow in xmlParseAttValueComplex
