NewCVE-2026-115817 (opens in a new tab)How to fix?
Upgrade Debian:unstable starman to version 0.4019-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream starman package and not the starman package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
Starman versions before 0.4019 for Perl allow a stalled request body to hold a worker indefinitely, as read_timeout 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 read_timeout to each wait for body data and adds a body_timeout limit, 300 seconds by default, on the total time to read a body.
