Mandriva Linux Security Advisory MDVSA-2012:023
http://www.mandriva.com/security/
_______________________________________________________________________

Package : libxml2
Date : February 22, 2012
Affected: 2010.1, 2011., Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

A vulnerability has been found and corrected in libxml2:

It was found that the hashing routine used by libxml2 arrays was
susceptible to predictable hash collisions. Sending a specially-crafted
message to an XML service could result in longer processing time,
which could lead to a denial of service. To mitigate this issue,
randomization has been added to the hashing function to reduce the
chance of an attacker successfully causing intentional collisions
(CVE-2012-0841).

The updated packages have been patched to correct this issue.
