 "Compaq is broadly distributing this Security Advisory in order
 to bring to the attention of users of Compaq products the
 important security information contained in this Advisory.
 Compaq recommends that all users determine the applicability of
 this information to their individual situations and take
 appropriate action.

 Compaq does not warrant that this information is necessarily
 accurate or complete for all user situations and, consequently,
 Compaq will not be responsible for any damages resulting from
 user's use or disregard of the information provided in this

- ----------------------------------------------------------------------

A potential  potential security vulnerability has been discovered
with the "at" and "inc" for Compaq's Tru64/DIGITAL UNIX software,
where under certain circumstances, an user may gain
unauthorized privileges.

- -----------------------------------------------------------------------

 This potential security problem has been resolved and a
 patch for this problem has been made available for
 Compaq's Tru64/DIGITAL  UNIX V4.0 to V4.0e

 *This solution will be included in the next distributed release of
  Compaq's Tru64/DIGITAL UNIX

The patch may be obtained from the World Wide Web at the
following FTP address:

    Use the Browse Patch Tree access option, select DIGITAL_UNIX
    directory then choose the appropriate version directory
    and download the patch accordingly.

  Note: [1]  The appropriate patch kit must be installed
        following any upgrade to V4.0a, V4.0b, or V4.0c,
      V4.0d, V4.0e.  If you upgrade from one version to
        another, i.e., V4.0b to V4.0d you should re-install
        these patches.

           [2]   IMPORTANT - Please review the appropriate
      release notes prior to installation of this patch.

 Additional Considerations:

   The following components are updated by these patches:

  /usr/bin/at           (the "at" command)
   /usr/bin/mh/inc      (The MH message handling system's "inc" command)
   /usr/shlib/libmh.so  (The MH shared library)

 If you believe you have, or aren't sure if you have, previously
 installed a patch to any of these modules you should contact your
 normal Compaq Services support channel.

 Compaq appreciates your cooperation and patience. We regret any
 inconvenience applying this information may cause.

 As always, Compaq urges you to periodically review your system
 management and security procedures.

  Compaq will continue to review and enhance the security
  features of its products and work with customers to maintain and
  improve the security and integrity of their systems.
