While researching the exploitability of a buffer overflow in
SSH up to version 1.2.27, we discovered a second buffer overflow
in the implmementation of the RSA algorithm in RSAREF2 from
RSA Data Security.

        To make this clear: in combination with the buffer overflow in rsaglue.c this makes possible to get
a remote shell on a machine running sshd AND it also makes possible to use a reverse exploit to gain access on
clients' machines, using malicious sshd.

PS: We are studding the possibility of using this buffer overflow alone, not in combination with rsaglue.c. What will 
make it possible to exploit it on patched ssh and sshd, and probably in OpenSSH
