PYSEC-2013-42

Quick fix

PYSEC-2013-42 — keystone: upgrade to the fixed version with the command below.

pip install --upgrade 'keystone>=2013.1.4'

Details

The (1) mamcache and (2) KVS token backends in OpenStack Identity (Keystone) Folsom 2012.2.x and Grizzly before 2013.1.4 do not properly compare the PKI token revocation list with PKI tokens, which allow remote attackers to bypass intended access restrictions via a revoked PKI token.
