This article discusses the recently discovered security hole in the crc32 attack detector as found in common ssh packages like OpenSSH and derivatives using the ssh-1 protocol. It is possible to exploit the crc32 hole to gain remote access to accounts without providing any password or to change login-uid if a valid account on the remote machine exists. Includes an exploit in the form of a set of patches to Openssh-2.1.1.
