Well, sort of. sendmail 8.6.12 jumps through all sorts of hoops
to limit the size of its syslog() output. You're right, of course,
that it really is a syslog() bug, and that's where the fix needs
to be. The output-limiting stuff in 8.6.12 is a hack, but it
*looks* as thought it would prevent this attack. For all the
obvious reasons, it's still essential to fix syslog(). Still, it
would have been more accurate to say:
The simple facts are:
- all sendmails are vulnerable, BUT some are much
more vulnerable than others.
