   Distribution:  Starman

Starman versions before 0.4019 for Perl allow a stalled request body to
hold a worker indefinitely, as read_timeout covers only the headers

Description
-----------
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.

Problem types
-------------
- CWE-770 Allocation of Resources Without Limits or Throttling

Solutions
---------
Upgrade to Starman 0.4019 or later.
