VNC: Client Cut Text Too Long
This protocol anomaly is a VNC client message with cut text that exceeds the user-defined maximum. The default cut text length is 4096; you can change this setting in the Sensor Settings Rulebase>Protocol Thresholds and Configuration>VNC>Cut text length.
Extended Description
The presence of an overly long VNC cut buffer datagram could indicate a network transmission error or that a buffer overflow exploitation is being attempted.
