UBUNTU-CVE-2026-115817: Medium severity ubuntu/starman vulnerability

Starman versions before 0.4019 for Perl allow a stalled request body to hold a worker indefinitely, as readtimeout covers only the headers. Content-Length and chunked request bodies are read with blocking reads and no deadline. A client that sends complete headers and then stalls or trickles the body keeps the worker waiting until it disconnects. A remote attacker can take every worker with a few such connections, five with the default worker count, so the server stops answering requests. Version 0.4019 applies readtimeout to each wait for body data and adds a bodytimeout limit, 300 seconds by default, on the total time to read a body.
