Details
As written in the advisory (Markdown source, shown as plain text).
### 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.
