LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks

A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange for both export and non-export grade cipher suites. An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lea...

OpenJDK: name for reverse DNS lookup used in certificate identity check (JSSE, 8067694)

A flaw was found in the way the JSSE component in OpenJDK performed X.509 certificate identity verification when establishing a TLS/SSL connection to a host identified by an IP address. In certain cases, the certificate was accepted as valid if it was issued for a host name to which the IP addres...
