Mandriva Linux Security Advisory MDVSA-2012:024
http://www.mandriva.com/security/
_______________________________________________________________________

Package : ruby
Date : February 28, 2012
Affected: 2010.1, 2011., Enterprise Server 5.0
_______________________________________________________________________

Problem Description:

A vulnerability has been found and corrected in ruby:

Ruby (aka CRuby) before 1.8.7-p357 computes hash values without
restricting the ability to trigger hash collisions predictably,
which allows context-dependent attackers to cause a denial of service
(CPU consumption) via crafted input to an application that maintains
a hash table (CVE-2011-4815).

The updated packages have been patched to correct this issue.
