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

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.
