REXEC: Username Buffer Overflow
This protocol anomaly triggers when it detects an REXEC connection with a specified remote user name that is too long. This can indicate a buffer overflow attempt.
Extended Description
An anomaly exists when an rexec command has a username that is too long. Receiving such a request may indicate an attack attempt. The impact of the flaw depends on how an rexecd daemon handles such malformed requests.
