===============================================================================
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.
