Mandriva Update for ruby MDVSA-2012:024 (ruby)

Please Install the Updated Packages.
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.
