概要

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. Users should upgrade their notation packages to v1.0.0-rc.6 or above.

Workarounds

User should use secure and trusted container registries.

NVD の説明

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.
