AIX 6.1 TL 8 : sendmail (IV75644) (Logjam)

The TLS protocol could allow a remote attacker to obtain sensitive information, caused by the failure to properly convey a DHEEXPORT ciphersuite choice. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to 512-bit export-grade cipher. Successful...

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...
