Recently I mentioned I'd been hacking about with a simple IMAP server.
Yesterday I was working on it some more, because the message store I've been testing against contains about 8 million messages and the damn thing is too slow.
During the course of some tweaking I discovered something interesting, every time a specific IMAP client connected to my server it crashed...
I spent a while fiddling around with backtraces and suchlike, but the upshot is I'm still not sure where the client crashes, but I've mailed some details to a few people to see if we can get it narrowed down.
I guess this counts as an accidental security issue. I wonder if I'll be able to collect a bounty? (Not that I'm bitter about past bounty-worthy reports being ignored ;)
Anyway interesting times, when I least expected them.
