[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.
