GHSA-785H-HRF7-GQXC Docker Notary Signature Algorithm Not Matched to Key vulnerability

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 Ed2551...

GHSA-8RJR-6QQ5-PJ9P Python RSA allows attackers to spoof signatures

The verify function in the RSA package for Python Python-RSA before 3.3 allows attackers to spoof signatures with a small public exponent via crafted signature padding, aka a BERserk attack...

GHSA-R9JW-MWHQ-WP62 PyJWT vulnerable to key confusion attacks

In PyJWT 1.5.0 and below the invalidstrings check in HMACAlgorithm.preparekey does not account for all PEM encoded public keys. Specifically, the PKCS1 PEM encoded format would be allowed because it is prefaced with the string -----BEGIN RSA PUBLIC KEY----- which is not accounted for. This enable...

GHSA-WRWF-PMMJ-W989 Observable Discrepancy in BouncyCastle

BouncyCastle TLS prior to version 1.0.3, when configured to use the JCE Java Cryptography Extension for cryptographic functions, provides a weak Bleichenbacher oracle when any TLS cipher suite using RSA key exchange is negotiated. An attacker can recover the private key from a vulnerable...
