Host denial of service via unbounded signature processing
Published Jun 6, 2023 · Updated Aug 2, 2024
Uncontrolled resource consumption in Notary Project Notation before 1.0.0-rc.6 allows remote attackers to cause host denial of service via notation verify. The verifier processes an unbounded number of registry signatures because maxSignatureAttempts has no effective default limit, allowing a malicious registry to keep supplying signatures. Exploitation requires a compromised or attacker-controlled registry and a user running verification, and the consequence is service interruption on the host.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
