--------------------------------------
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.
