Description Mark J. Cox 2006-07-11 09:37:45 UTC 
Ubuntu reported a possible Mailman DoS where a malformed message can cause the
mailman server to stop sending out email.  Currently embargoed with no proposed
date.

Also may affect RHEL3, RHEL2.1

Proposed patch from Ubuntu
Comment 3 Mark J. Cox 2006-07-11 11:05:12 UTC 
embargo 20060718 1400 UTC
Comment 6 Mark J. Cox 2006-07-18 12:32:53 UTC 
Embargo may be extended by request of Barry Warsaw.  Please don't open this bug
at this time.
Comment 7 Harald Hoyer 2006-07-21 14:10:35 UTC 
Ok, wrote some test cases. RHEL3 and RHEL4 are _NOT_ vulnerable, cause
python-2.3.4-14 has a email/Message.py which does not backtrace with strange
filenames.
Comment 8 Harald Hoyer 2006-07-21 14:32:31 UTC 
RHEL3's python-2.2.3-5 also does not backtrace..
Comment 9 Harald Hoyer 2006-07-21 15:06:03 UTC 
mailman from RHEL2.1 does not save attachements and does not parse any mime
message headers.
Comment 10 Harald Hoyer 2006-07-21 15:07:13 UTC 
RHSA-2006:0600 is free for other things... sorry about the false alarm. I just
checked, if the patch would apply.
Comment 11 Harald Hoyer 2006-07-21 15:46:15 UTC 
ok, now I have a better testcase... :-/ traceback..
