  "details" : [ "The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the \"Logjam\" issue.", "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 lead to a passive man-in-the-middle attack in which the attacker is able to decrypt all traffic." ],
  "statement" : "This issue affects the version of openssl and nss libraries as shipped with Red Hat Enterprise Linux 4, 5, 6 and 7. More information about this flaw is available at: https://bugzilla.redhat.com/show_bug.cgi?id=1223211#c4 and https://bugzilla.redhat.com/show_bug.cgi?id=1223211#c5.\nRed Hat Enterprise Linux 4 is in Extended Life Cycle phase of the support and maintenance life cycle. This issue is not currently planned to be addressed in future updates of Red Hat Enterprise Linux 4.",
