===============================================================================

SUMMARY:

    There are multiple vulnerabilities in IBM SDK Java Technology Edition,
    versions 5, 6, 7, 7.1 that are used by AIX. These issues were disclosed as
    part of the IBM Java SDK updates in July 2015.

    This bulletin also addresses the Logjam Attack on TLS connections using the
    Diffie-Hellman (DH) key exchange protocol affects.


===============================================================================

VULNERABILITY DETAILS:

    CVEID: CVE-2015-4000
    DESCRIPTION: The TLS protocol could allow a remote attacker to obtain
        sensitive information, caused by the failure to properly convey a
        DHE_EXPORT 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 exploitation could allow
        an attacker to recover the session key as well as modify the contents
        of the traffic. This vulnerability is commonly referred to as
        "Logjam".

        You should verify applying this configuration change does not cause
        any compatibility issues. If you change the default setting after
        applying the fix, you will expose yourself to the attack described
        above. IBM recommends that you review your entire environment to
        identify other areas where you have enabled the Diffie-Hellman
        key-exchange protocol used in TLS and take appropriate mitigation and
        remediation actions.

    WORKAROUNDS AND MITIGATIONS:

        None.
