> 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.
