CVE-2023-33957: Uncontrolled Resource Consumption

June 6, 2023 (updated July 2, 2023)

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 inspect 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 are advised to upgrade. Users unable to upgrade may restrict container registries to a set of secure and trusted container registries.
