Description GLSAMaker/CVETool Bot gentoo-dev 2012-11-28 23:03:15 UTC 
CVE-2012-5370 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-5370):
  JRuby computes hash values without properly 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, as demonstrated by a
  universal multicollision attack against the MurmurHash2 algorithm, a
  different vulnerability than CVE-2011-4838.
Comment 1 Hans de Graaff gentoo-dev Security 2013-12-22 16:23:40 UTC 
As far as I can tell this is fixed in jruby 1.7.1, but we are still providing 1.6.x.
Comment 2 Hans de Graaff gentoo-dev Security 2014-09-02 05:35:03 UTC 
jruby 1.6 is now masked for removal.

Thank you

jruby 1.6.x was removed some time ago.

Per previous comments the vulnerable version was removed.  Following links verify that:
