OpenStack Keystone Denial of Service vulnerability via a large HTTP request
OpenStack Keystone Grizzly before 2013.1, Folsom, and possibly earlier allows remote attackers to cause a denial of service (CPU and memory consumption) via a large HTTP request, as demonstrated by a long tenant_name when requesting a token.
This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality none, integrity none, availability high.
