By sending ec2tokens and s3tokens endpoints a valid AWS Signature, an unauthenticated attacker may obtain Keystone authorization, resulting in unauthorized access and privilege escalation. Swift also needed to be patched to work with the fixed version of keystone. One is advised to first update swift and then keystone. For Debian 11 bullseye, this problem has been fixed in version 2:18.1.0-1+deb11u2. We recommend that you upgrade your keystone packages.
