ircii-pana (BitchX) 74p4 overflow

[lcamtuf () BOSS STASZIC WAW PL (Michal Zalewski)]

Recently I found interesting overflow in dgets(...) function in one of the
most popular irc clients, BitchX 74p4 (by panasync). You can cause remote
client crash (and possibly much more) when you're fingered (/finger
built-in command) by victim - simply create eg. .plan with line longer
than 2 kbytes.  Depending on used line (ln /dev/urandom ~/.plan is nice),
client will crash with SEGV immediately or during any next '/' command...

Dumb, isn't it? For test purposes, /finger lcamtuf () shadow mud pl
