JRuby Hash Collision Denial of Service Vulnerability

CVE-2012-5370 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
