             Summary: If Proton receives a frame with an unexpected performative number it will SEGV
                 Key: PROTON-590
                 URL: https://issues.apache.org/jira/browse/PROTON-590
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c
    Affects Versions: 0.7
            Reporter: Andrew Stitcher
            Assignee: Andrew Stitcher


The processing for incoming frames dispatches based in the integer number of the performative. To do this it uses a table which is initially zero filled.

On initialising a connection it fills out the table entries for performatives that it can handle, but leaves the others zero.

On an incoming frame it will call the routine in the table entry without checking if it is zero. So if it gets an unrecognised performative integer it will call through a zero pointer causing a SEGV.
