Also known as:GHSA-9m3v-v4r5-ppx7GO-2023-1829

Description

### 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.
