- -------------------------------------------------------------------------
I.
   A. Background
      This problem was originally reported in CERT Advisory CA-99-05,
      regarding the vulnerability in automountd which allows an
      intruder to execute arbitrary commands with the privileges of
      the automountd process.

      We had previously reported that Hewlett-Packard platforms were
      not vulnerable; we now have new information showing that we
      are indeed vulnerable.

**REVISED 01**
   B.| Fixing the problem
     |
     | For HP-UX release 11.00  apply             PHNE_20371,
     | for HP-UX release 10.20  apply             PHNE_20628.
     |
     | NOTE:  There are various patch dependencies associated with
     |        this patch, and rebooting is required.
