Hello,

this problem has been reported to IBM Lotus customer support
(PMR 37321,999,724) on Feb 16, 2004 and was reproduced by them.

Affected versions:
Domino 6.5.1 and newer on Linux (other platforms not tested by me, but
Domino 6.5.1 on Windows has been found to be vulnerable too by IBM
support)

Abstract:
Opening certain mails via Domino Web Access leads to a crash of the whole
Domino-server.

Detailed description:
Open your favourite mail-program (eg. pine) and write a message to a
person reading his mail via Domino Web Access (formerly known as
iNotes) with the following message content:
(just paste all the lines below into the body of the mail)

--- snip here; do not paste this line --
Content-Disposition: Attachment; filename="PC210017.JPG"
Content-Type: image/jpeg;
 Name="PC210017.JPG"
Content-Transfer-Encoding: Base64

AgAJAAAA6AAAADIBAgAUAAAACAEAABMCAwABAAAAAgAAAGmHBAABAAAAHAEAAAADAABPTFlN
[Add here some megabytes of data. 1kB is not enough, but 12MB was
sufficient in all my tests]
--- snip here; do not pste this line ---

As soon as the recipient opens the mail in Domino Web Access, the whole
Domino server will go down.

Solution:
There is no solution provided by IBM and they are not planning to fix the
problem. The proposed workaround is to limit the maximum message-size or
to disable the web-access.
