Does this matter?
Lower severity and a low EPSS score (1.94%). Track it; it rarely justifies an emergency change on its own.
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.
