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.

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 :-)

I'm not sure why we just didn't do what david suggested.

david, should we back out
Comment 7 User image David :Bienvenu 2004-05-19 20:02:05 PDT
yes, we should back it out, just to remove the unneeded code and simplify it.

Comment 13 User image (not reading, please use instead) 2004-05-29 17:04:53 PDT
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.

Removing security-sensitive flag for bugs on the known-vulnerabilities list
Comment 21 User image Karen Huang 2004-07-22 10:43:15 PDT
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....
