What is CVE-2012-5372?

Official description
Rubinius 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 MurmurHash3 algorithm.
Weakness: CWE-310
Which versions are affected by CVE-2012-5372?
