openssl: NETSCAPE_REUSE_CIPHER_CHANGE_BUG ciphersuite downgrade attack

OpenSSL before 0.9.8q, and 1.0.x before 1.0.0c, when SSLOPNETSCAPEREUSECIPHERCHANGEBUG is enabled, does not properly prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the downgrade to an unintended cipher via vectors involving sniffing network...

OpenSSL 1.0.0 < 1.0.0c Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.0c. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.0c advisory. - OpenSSL before 1.0.0c, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allo...
