RSA BSAFE SSL-J versions prior to 6.2.4 contain a heap inspection vulnerability that could allow an attacker with physical access to the system to recover sensitive key material. RSA BSAFE SSL-J versions prior to 6.2.4 contain a covert timing channel vulnerability during RSA decryption, also known as a Bleichenbacher attack on RSA decryption. A remote attacker may be able to recover a RSA key. RSA BSAFE Crypto-J versions prior to 6.2.4 and RSA BSAFE SSL-J versions prior to 6.2.4 contain a covert timing channel vulnerability during PKCS #1 unpadding operations, also known as a Bleichenbacher attack. A remote attacker may be able to recover a RSA key.
