Details

Guang Yee discovered that Keystone would not always perform all
verification checks when configured to use PKI. If the keystone server was
configured to use PKI and services or users requested online verification,
an attacker could potentially exploit this to bypass revocation checks.
Keystone uses UUID tokens by default in Ubuntu.
