Source: keystone
Architecture: source
Version: 2:22.0.2-0+deb12u1
Distribution: bookworm-security
Urgency: medium
Maintainer: Debian OpenStack <team+openstack@tracker.debian.org>
Changed-By: Thomas Goirand <zigo@debian.org>
Changes:
keystone (2:22.0.2-0+deb12u1) bookworm-security; urgency=medium
.
* New upstream release.
* Blacklist failing SAMLGenerationTests test:
- test_sign_assertion_logs_message_if_xmlsec1_is_not_installed
* Add xmlsec1 as build-depends.
* kay reported a vulnerability in Keystone’s ec2tokens and s3tokens APIs. By
sending those endpoints a valid AWS Signature (e.g., from a presigned S3
URL), an unauthenticated attacker may obtain Keystone authorization
(ec2tokens can yield a fully scoped token; s3tokens can reveal scope
accepted by some services), resulting in unauthorized access and privilege
escalation. Deployments where /v3/ec2tokens or /v3/s3tokens are reachable
by unauthenticated clients (e.g., exposed on a public API) are affected.
Applied upstream patch (Closes: #XXXXXXX):
- Consistent_and_Secure_RBAC_Phase_1.patch
- Fix_policies_for_groups.patch
- Allow_admin_to_access_tokens_and_credentials.patch
- Dont_enforce_when_HTTP_GET_on_s3tokens_and_ec2tokens.patch
- keystone-bug-2119646-stable-2024.1.patch (backported by me)
