Description of problem:
After performing three RH 6.2->7.3 upgrades, and installing the update RPMS, the
systems behaved oddly.  After reboot, 'ps ax' showed the following:

29528 ?        S      0:00 [sendmail]

 5685 ?        S      0:00 [sendmail]
 5687 ?        S      0:00 [mimedefang]
 5690 ?        S      0:00 [mimedefang]

However, at the time, the system was using _no_ swap.

Downgrading to kernel-2.4.18-24.7.x fixes this.

Comment 1 Daniel Rogers 2003-03-26 19:20:21 UTC
Also, kernel-2.4.18-26 is not affected by this.


Comment 2 Arjan van de Ven 2003-03-27 08:54:52 UTC
the ps output is limited because these are setuid apps, and with the ptrace fix
we had to tighten getting info from such apps. Getting all kinds of info from
such sensitive apps is a sensitive security issue; the update went to the other
side of cautious and we'll be looking at if we can relax the checking a bit in
the future; it's as clear cut as it might look though  :(

Comment 3 Daniel Rogers 2003-03-27 17:18:31 UTC
Ok, thanks.  I suspected it was something along those lines.

It's annoying on the ps display, but it was also causing a problem with the
mimedefang init script, as 'pidof' wasn't able to find the
'mimedefang-multiplexor' process, as the name was being truncated.

Dan.

Comment 6 Eric Hagberg 2003-05-01 17:42:37 UTC
Actually, it isn't just setuid processes. sendmail doesn't show up as bracketed
(it is running as root) and is setuid. nscd shows up bracketed and isn't setuid.

Does this have more to do with how the process is started? I see jserver,
cserver, cannaserver, kserver, tserver and xfs bracketed, but none are setuid,
just running as a non-root id.



Comment 10 Bugzilla owner 2004-09-30 15:40:42 UTC
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
persists.

The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, 
and if you believe this bug is interesting to them, please report the problem in
the bug tracker at: http://bugzilla.fedora.us/
