------------------------------------------------------------------------- Debian LTS Advisory DLA-4367-1 [email protected] https://www.debian.org/lts/security/ Carlos Henrique Lima Melara November 07, 2025 https://wiki.debian.org/LTS

Package : keystone Version : 2:18.1.0-1+deb11u2 CVE ID : not yet available Debian Bug : 1120053

A vulnerability was found in keystone, the identity service used by OpenStack.
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.
