An unauthenticated peer could repeat the KEXINIT and cause allocation of up to 384MB(not 128MB that the official said). In the default case, an attacker can build 100 such connections, which will consume 38400 MB of memory on the server. The patch is here: http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/kex.c?rev=1.127&content-type=text/x-cvsweb-markup -- Regards, Shi Lei / Gear Team, Qihoo 360 Inc.
