The ssl3getkeyexchange function in s3clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct ECDHE-to-ECDH downgrade attacks and trigger a loss of forward secrecy by omitting the ServerKeyExchange message...

CVE-2015-0204

The ssl3getkeyexchange function in s3clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct RSA-to-EXPORTRSA downgrade attacks and facilitate brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to...

PolarSSL Weak Signature Algorithm Negotiation

PolarSSL 1.3.8 does not properly negotiate the signature algorithm to use, allowing remote attackers to conduct downgrade attacks. This plugin sends a list of hash algorithms SHA512, SHA384, SHA256, SHA224, SHA1, and MD5 in descending order, and checks if the server selects MD5. TRUSTED...
