https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=257368 --- Comment #5 from johannes@jo-t.de --- Truss for ggatec: debug: Received hdr packet. write(1,"debug: Received hdr packet.\n",28) = 28 (0x1c) recvfrom(4,0x7fffdffddf40,2147467264,MSG_WAITALL,0x0,0x0) ERR#14 'Bad address' debug: Received data packet. write(1,"debug: Received data packet.\n",29) = 29 (0x1d) error: Lost connection 4. Notice the bad address! It's supposed to point to a stack buffer of size 128kB. But here we are trying to dump 2 GB into it. Oops. Stack buffer overflow.
