Subject [jira] [Created] (PROTON-976) pn_read_frame does not validate frame offset
Date Thu, 06 Aug 2015 12:25:05 GMT
Ken Giusti created PROTON-976:
---------------------------------

             Summary: 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.
