running on the remote host.  As such, it is reportedly affected by
multiple flaws :

  - Provided Performance Monitoring Infrastructure (PMI) is
    enabled, it may be possible for a local attacker to
    obtain sensitive information through 'Systemout.log' and
    'ffdc' files that are written by PerfServlet.

  - SSL Configuration settings attribute 'Security Level'
    does not correctly enforce the level of encryption used
    by the application server. (PK63182)");
