[Security] Bump puma and capistrano3-puma

[dependabot-preview[bot]]

Bumps puma and capistrano3-puma. These dependencies needed to be updated together. Updates puma from 3.12.6 to 5.4.0 This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Keepalive Connections Causing Denial Of Service in puma This vulnerability is related to CVE-2019-16770.

Impact

The fix for CVE-2019-16770 was incomplete. The original fix only protected existing connections that had already been accepted from having their requests starved by greedy persistent-connections saturating all threads in the same process. However, new connections may still be starved by greedy persistent-connections saturating all threads in all processes in the cluster.

A puma server which received more concurrent keep-alive connections than the server had threads in its threadpool would service only a subset of connections, denying service to the unserved connections.

Patches

This problem has been fixed in puma 4.3.8 and 5.3.1.

Workarounds

Setting queue_requests false also fixes the issue. This is not advised when using puma without a reverse proxy, such as nginx or apache, because you will open yourself to slow client attacks (e.g. slowloris).

The fix is very small. A git patch is available here for those using unsupported versions of Puma.
