Last modified

CVE-2011-4815 is a vulnerability of currently unknown severity. Ruby (aka CRuby) before 1.8.7-p357 computes hash values without 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.. EPSS estimates a 4.25% chance of exploitation in the next 30 days.
