Description Jan Lieskovsky 2012-12-03 10:41:19 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2012-6051 to the following vulnerability:

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.
