VNC: Set Encodings Overflow
This protocol anomaly is a VNC message with an encoding type buffer that exceeds the length specified in the SetEncodings VNC client message.
Extended Description
RFB datagrams containing encoding-type values greater than 16 constitute a protocol anomaly. This condition could indicate a network configuration error. It could also indicate an attacker is attempting to cause a buffer overflow by injecting malformed packets into the network.
