             Summary: Disposition frames can take a *very* long time to complete
                 Key: PROTON-1978
                 URL: https://issues.apache.org/jira/browse/PROTON-1978
             Project: Qpid Proton
          Issue Type: Bug
          Components: proton-c
            Reporter: Andrew Stitcher
            Assignee: Andrew Stitcher


This bug was found by the oss-fuzz project: [https://oss-fuzz.com/testcase?key=5118747114209280|http://example.com/]

If the last delivery value affected is legitimate (before the next sequence number to be assigned), but the first value is hugely before it then the disposition frame handling will loop through every affected delivery number from first to last which can take a very long time and effectively hang the process.
