CVE-2012-5372: Rubinius

Medium severity, CVSS 5.0. EPSS: 1.9% chance of exploitation in the next 30 days.

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.
