Nothing limits the length of the run, which can span several reads.</p> <p>A remote attacker can occupy a worker for about a minute of CPU time with one 128 KiB request, before the application is called.</p> <p>Starlet versions from 0.20 before 0.33 for Perl allow CPU exhaustion via regular expression backtracking when decoding chunked request bodies.</p> <p>A chunk-size line is matched as a run of hex digits, then .* and a CRLF.
