[jira] [Created] (PROTON-2968) pn_decoder_decode rejects compound counts too large for the node array

Andrew Stitcher created PROTON-2968:
---------------------------------------

             Summary: pn_decoder_decode rejects compound counts too large for the node array
                 Key: PROTON-2968
                 URL: https://issues.apache.org/jira/browse/PROTON-2968
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c
            Reporter: Andrew Stitcher
            Assignee: Andrew Stitcher
             Fix For: proton-c-0.41.0


Elements of a zero width type (null, true, ...) take up no input bytes at
all, so the count in an array header is not bounded by the size the header
declares, the way a list's would be.

No array with a count larger than the maximum allowed would be decoded into the node array, so reject the count outright as soon as the header is read, with PN_OUT_OF_MEMORY - which is what a decode that ran out of nodes would report anyway.
