more to do for bug #157644...

dan got email from, pointing out that the fix for #157644
plugged one security hole, but not them all.

from the reporter:

the correct fix is to limit the number of messages to (MAXINT(sizeof(Pop3MsgInfo))

if an evil server sends a larger number of messages, we'll only allocate space
for 50k.  but if part way through the list, if the server introduces a message
that is < than the max but > 50k, we'll allocate more space.

SendUidl() doesn't bounds check on the 50k message limit.

the patch in bug #157644 assumes that message numbers are sequential.

I've got the complete email from zen-parse.
giving zen-parse ( access to this new bug.
As far as I can tell, this is our only open bug which would allow a remote
server to take control of a Mozilla session. 'twould be nice if we could fix it :-)

yes, we should back it out, just to remove the unneeded code and simplify it.
Fix got approvals on 5/19, is it checked in?

over to david who has the fix and is going to land on trunk (he already landed
on the branch).

I'll log a bug about backing out bug #157644.

note, if we need to test this we can use servterm to emulate an evil pop server.

Since David mentioned that this bug need to be verified in the debugger, by
tweaking some values at runtime...
I had requested Seth to help for verifying this bug for 1.7....
