CVE-2015-9258: Docker Notary Signature Algorithm Not Matched to Key vulnerability

May 14, 2022 (updated August 2, 2023)

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.
