Erroneously using an all-zero seed for RSA-OEAP padding instead of the generated random bytes, in Oberon microsystems AG’s Oberon PSA Crypto library in all versions up to 1.5.1, results in deterministic RSA and thus in a loss of confidentiality for guessable messages, recognition of repeated messages, and loss of security proofs.
