CVE-2012-5370

UnknownEPSS 2.25%

Last modified

CVE-2012-5370 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.25% chance of exploitation in the next 30 days.
