===============================================================================
[8lgm]-Advisory-16.UNIX.sendmail-6-Dec-1994.UPDATE
PROGRAM:
sendmail(8)
UPDATE:
After further investigation, it has been discovered that SVR4 based
ports include sendmail(8) based on SMI code. This code therefore
is affected by the problem discussed in:
[8lgm]-Advisory-16.UNIX.sendmail-6-Dec-1994
Any systems running SMI sendmail(8) should follow advice given in
this advisory, and remove any set bits on sendmail(8).
To give more time to administrators to fix this problem, and due
to other problems being published this week, the exploit script
will now be posted at 00:00GMT on Monday 6th February 1995.
To retrieve these details, send a mail containing the line:
send [8lgm]-Advisory-16.UNIX.sendmail-6-Dec-1994-EXPLOIT
to 8lgm-fileserver@bagpuss.demon.co.uk. Requests for the script
to be sent before this date will be directed to /dev/null.
FIX:
We recommend that security conscious sites upgrade immediately
to UCB Sendmail 8.6.9, as Suns sendmail is generally recognised
as being broken. Your options are:
1. Obtain patch from your vendor.
2. Build and install sendmail 8.6.9, available from:
ftp.cs.berkeley.edu:/ucb/sendmail/sendmail.8.6.9.*
3. Remove set bits from any SMI sendmail(8) binaries.
