OpenSSL -- CMS and S/MIME Bleichenbacher attack

The OpenSSL Team reports: A weakness in the OpenSSL CMS and PKCS 7 code can be exploited using Bleichenbacher's attack on PKCS 1 v1.5 RSA padding also known as the million message attack MMA. Only users of CMS, PKCS 7, or S/MIME decryption operations are affected. A successful attack needs on...
