      Title:  Security Advisory regarding automountd

-------------------------------------------------------------------------
      HEWLETT-PACKARD COMPANY SECURITY ADVISORY: #00104, 21 Oct. 99
-------------------------------------------------------------------------

The information in the following Security Advisory should be acted upon
as soon as possible.  Hewlett-Packard Company will not be liable for any
consequences to any customer resulting from customer's failure to fully
implement instructions in this Security Advisory as soon as possible.

-------------------------------------------------------------------------
PROBLEM:  automountd can run user programs as root.

PLATFORM: HP-9000 Series 700/800 HP-UX releases 10.X and 11.00.

DAMAGE:   Allows users to gain root privileges

SOLUTION: Temporarily set AutoFS = 0 in  /etc/rc.config.d/nfsconf
          (see below)

AVAILABILITY: No patches for 10.X and 11.00 are available at this time.
          NOTE: This advisory will be revised when patches are available.
-------------------------------------------------------------------------
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.

   B. Fixing the problem -
      At this time there are no patches available for any releases.

      As a work around, setting AutoFS = 0 in the file
      /etc/rc.config.d/nfsconf,  we believe, will disallow most
      exploitations.  We continue to work on this problem and this
      advisory will be updated when patches become available.
