Whats a protocol parser?
A protocol parser is a plug-in module for Netmon that knows how to interpret the data packets, or frames, for a particular protocol. Suppose you received a frame of data and wanted to interpret it. One way to do this would be to read the initial part of the frame and identify the protocol in use, then consult a reference that lists the size and meaning of each field in a frame from that protocol. Once you had this information, you could interpret the frame, but this clearly is a task that cries out for automation, and Netmon’s protocol parsers are designed to do this work. Netmon includes a collection of parsers, each of which knows how to interpret the frames for a particular protocol. Netmon provides parsers for more than 100 different protocols, depending on the version. Most parsers are not affected by the vulnerability, but a number of them are.
