Detail
A vulnerability in libssh could allow an unauthenticated, remote attacker to bypass authentication on a targeted system. The vulnerability is due to improper authentication operations by the server-side state machine of the affected software. An attacker could exploit this vulnerability by presenting a SSH2_MSG_USERAUTH_SUCCESS message to a targeted system. A successful exploit could allow the attacker to bypass authentication and gain unauthorized access to a targeted system. This advisory will be updated as additional information becomes available.
