OpenSSH ssh-1 exploit

by platon on February 26th, 2001 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. By Paul Starzetz
