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.
