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: #1120053): - Fix_oslo_policy_DeprecatedRule_warnings.patch - 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) - compat-with-oslo.policy-3.5.0.patch Checksums-Sha1: 3da3a3427e828d0d36115c4ccb2fc3981ff091e6 3635 keystone_18.1.0-1+deb11u2.dsc 1830ea306eb207ef120d4d14d3dac07eeecc9bb3 1072716 keystone_18.1.0.orig.tar.xz b6462b263821ffcaad05d3334089b6465f845ece 64116 keystone_18.1.0-1+deb11u2.debian.tar.xz e68bf47463a7c7be98e6b5f36ca7a4dd5eab4b76 17551 keystone_18.1.0-1+deb11u2_amd64.buildinfo Checksums-Sha256: 5c99fa4cd47d987d344ec5d7e8b6cfd4ada05d265cc1e0256a8c6c0daebb0cf3 3635 keystone_18.1.0-1+deb11u2.dsc d1509347f8686179c78e347718754b81f882adc2efe8296bb4d18b0c3dc9336e 1072716 keystone_18.1.0.orig.tar.xz 38962e460daee25affca32c445d82067f04896135e8ff97fe71a9602471fce0e 64116 keystone_18.1.0-1+deb11u2.debian.tar.xz 85b72faea86ba63c66fee9b9f81158a08688fc37164719171a39b5c74f4d5bce 17551 keystone_18.1.0-1+deb11u2_amd64.buildinfo Files: e271bd81c995e17cf7334feafcc05255 3635 net optional keystone_18.1.0-1+deb11u2.dsc 4de2704a30c410082685052e5b508b1c 1072716 net optional keystone_18.1.0.orig.tar.xz 929f7dad13cfae565be1e898acb7f4a0 64116 net optional keystone_18.1.0-1+deb11u2.debian.tar.xz cbda147bc13848c704b8ee101b780292 17551 net optional keystone_18.1.0-1+deb11u2_amd64.buildinfo
