notation is a CLI tool to sign and verify OCI artifacts and container images. An attacker who has compromised a registry and added a high number of signatures to an artifact can cause denial of service of services on the machine, if a user runs notation verify command on the same machine. The problem has been fixed in the release v1.0.0-rc.6. Users should upgrade their notation packages to v1.0.0-rc.6 or above. Users unable to upgrade may restrict container registries to a set of secure and trusted container registries.

### Impact An attacker who controls or compromises a registry can make the registry serve an infinite number of signatures for the artifact, causing a denial of service to the host machine running `notation verify`. ### Patches The problem has been fixed in the release [v1.0.0-rc.6](https://github.com/notaryproject/notation/releases/tag/v1.0.0-rc.6). Users should upgrade their notation packages to [v1.0.0-rc.6](https://github.com/notaryproject/notation/releases/tag/v1.0.0-rc.6) or above. ### Workarounds User should use secure and trusted container registries ### Credits The `notation` project would like to thank Adam Korczynski (@AdamKorcz) for responsibly disclosing the issue found during an security audit (facilitated by OSTIF and sponsored by CNCF) and Shiwei Zhang (@shizhMSFT) for root cause analysis.
