Vulnerability details
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
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.
