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. richie 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 -- A390 1BBA 2C58 D679 5A71 - 86F9 404F 4B53 3944 C2D0 Investigacion y Desarrollo - CoreLabs - Core SDI http://www.core-sdi.com --- For a personal reply use gera@core-sdi.com
