Security Bulletin
Summary
When a trustor issues a trust token with impersonation enabled, the token is only added to the trustor's token list and not to the trustee's token list. This scenario results in the trust token not being invalidated by the trustee's token revocation (bulk revocation). It is most noticeable when the trustee user is disabled
or the trustee changes a password. Only setups using the memcache backend for tokens in Keystone are affected.
