The previous fix prevents remote users mailing getting a local shell,
however it is still possible for a local user to run sendmail by hand
and exploit the hole (and get a non-root shell).
Those who are worried by this may wish to take advantage of the following:

   It may be worth making a safe Sun binary available by anon Blue-Book
   FTP and putting a uuencoded version in an info-server too.

   I have put two binaries in the 'guest' file area on uk.ac.brunel.me:
   (Username guest, any passwd)

   <FTP>sun-sendmail-IDA
   <FTP>pyr-sendmail-IDA

   Both are IDA-sendmail, compiled without DEBUG or WIZ. The Sun version
   was compiled under SunOs 3.3 and also runs under 4.0. Vanilla versions
   would be more useful to most people though.
