CVE-2012-6051: Google Cityhash

Medium severity, CVSS 5.0. EPSS: 0.6% chance of exploitation in the next 30 days.

Google CityHash 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.
