Package : keystone
CVE ID : not yet available
A vulnerability was discovered in the ec2tokens and s3tokens APIs of
Keystone, the OpenStack identity service, which may result in
authorisation bypass or privilege escalation if /v3/ec2tokens or
/v3/s3tokens are reachable by unauthenticated clients.
The Swift object storage service also requires an update to work with
the updated Keystone: The update to Swift is provided as 2.30.1-0+deb12u1
for bookworm and 2.35.1-0+deb13u1 for trixie and is backwards-compatible
with older Keystone versions. As such, it is recommended to first upgrade
Swift before deploying the Keystone update.
For the oldstable distribution (bookworm), this problem has been fixed
in version 2:22.0.2-0+deb12u1.
For the stable distribution (trixie), this problem has been fixed in
version 2:27.0.0-3+deb13u1.
We recommend that you upgrade your keystone packages.
