freeSSHd Key Exchange Buffer Overflow

Vulnerability Assessment Summary
Checks for a buffer overflow in freeSSHd

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote SSH server is prone to a buffer overflow vulnerability.

Description :

The remote host is using freeSSHd, a free SSH server for Windows.

The version of freeSSHd installed on the remote host does not validate
the key exchange strings sent by a SSH client. This can result in a
buffer overflow and possibly a compromise of the host if an
unauthenticated attacker sends a long key exchange string.
