SYSTEMS AFFECTED

    AIX

PROBLEM

    Klaus Kusche found following.  "techlibss" is the program used  to
    install IBM's  monthly AIX  service CD's.   The program  is run as
    "root" and creates log files with a fixed name in /tmp using shell
    redirection.   Hence,  it  happily  follows  any existing symbolic
    link with that name, blindly overwriting any file the link happens
    to point to.

SOLUTION

    The problem is fixed with the fileset  techlib.service.rte.1.0.0.4
    on the service CD  for Jan 2000.   If you have installed  an older
    version of "techlib.service.rte", upgrade manually (following  the
    instructions on the CD cover), because that fileset is not updated
    automatically,  even  if  you  choose  to automatically update all
    installed AIX filesets from the CD.
