FKIE_CVE-2012-5370

Vulnerability from fkie_nvd - Published: 2012-11-28 13:03 - Updated: 2025-04-11 00:51
Severity ?
Summary
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.
