 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.
