PROTON-976: verify frame header before parsing
Proton-J fixes authored by Robert Gemmell <rob...@apache.org>
> pn_read_frame does not validate frame offset
> --------------------------------------------
>
> Key: PROTON-976
> URL: https://issues.apache.org/jira/browse/PROTON-976
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.10
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Blocker
> Fix For: 0.10
>
>
> pn_read_frame in framing.c does not validate the doff with respect to the
> frame size. If doff is corrupt proton will still attempt to parse the frame.
> This can result in a crash.
> I consider this a blocker as an attacker can craft a bad frame that results
> in crashing the receiver.
