SSL/TLS: Cross-protocol attack on TLS using SSLv2 (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker could potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack ...

openssl: assertion failure in SSLv2 servers

A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled...

OpenSSL: SSLv2 doesn't block disabled ciphers

A flaw was found in the way malicious SSLv2 clients could negotiate SSLv2 ciphers that were disabled on the server. This could result in weak SSLv2 ciphers being used for SSLv2 connections, making them vulnerable to man-in-the-middle attacks...
