security flaw

The SSL and TLS components for OpenSSL 0.9.6i and earlier, 0.9.7, and 0.9.7a allow remote attackers to perform an unauthorized RSA private key operation via a modified Bleichenbacher attack that uses a large number of SSL or TLS connections using PKCS 1 v1.5 padding that cause OpenSSL to leak...

Cryptographic libraries and applications do not adequately defend against timing attacks

Overview Cryptographic libraries and applications do not provide adequate defense against a side-channel timing attack against RSA private keys. Such an attack has been shown to be practical using currently available hardware on systems and networks with sufficiently low variance in latency...
