  Compaq has discovered a potential vulnerability with the 
  "at" and "inc" for Compaq's DIGITAL UNIX  software, where under certain 
  circumstances, an user may gain unauthorized privileges. 
  
----------------------------------------------------------------------
RESOLUTION:

 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:

    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.

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