According to its self-reported version, IOS is affected by a vulnerability in the Secure Shell (SSH) server code due to an internal state not being represented correctly in the SSH state machine, which leads to an unexpected behavior.
An authenticated, remote attacker can exploit this, by creating an SSH connection and using a specific traffic pattern that causes an error condition within that connection. A successful exploit can cause the affected device to reload, resulting in a denial of service (DoS) condition.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
