Description

In Docker Notary before 0.1, gotuf/signed/verify.go has a Signature Algorithm Not Matched to Key vulnerability. Because an attacker controls the field specifying the signature algorithm, they might (for example) be able to forge a signature by forcing a misinterpretation of an RSA-PSS key as Ed25519 elliptic-curve data.

Affected products

• Docker Notary: before 0.1 — fixed in 0.1

How to fix

Upgrade to a fixed version: Docker Notary 0.1. Check the vendor advisory for mitigations.
