GSD-2019-16770

Vulnerability from gsd - Updated: 2019-12-05 00:00

Details

A poorly-behaved client could use keepalive requests to monopolize Puma's reactor and create a denial of service attack. If more keepalive connections to Puma are opened than there are threads available, additional connections will wait permanently if the attacker sends requests frequently enough.

GHSA-7XX3-M584-X994

Vulnerability from github – Published: 2019-12-05 19:26 – Updated: 2021-01-08 19:12

Summary

A poorly-behaved client could use keepalive requests to monopolize Puma's reactor and create a denial of service attack

Details

Keepalive thread overload/DoS

Impact

A poorly-behaved client could use keepalive requests to monopolize Puma's reactor and create a denial of service attack.

If more keepalive connections to Puma are opened than there are threads available, additional connections will wait permanently if the attacker sends requests frequently enough.

Patches

This vulnerability is patched in Puma 4.3.1 and 3.12.2.

Workarounds

Reverse proxies in front of Puma could be configured to always allow less than X keepalive connections to a Puma cluster or process, where X is the number of threads configured in Puma's thread pool.

CVE-2019-16770 (GCVE-0-2019-16770)

Vulnerability from cvelistv5 – Published: 2019-12-05 19:35 – Updated: 2024-08-05 01:24

Summary

In Puma before versions 3.12.2 and 4.3.1, a poorly-behaved client could use keepalive requests to monopolize Puma's reactor and create a denial of service attack. If more keepalive connections to Puma are opened than there are threads available, additional connections will wait permanently if the attacker sends requests frequently enough. This vulnerability is patched in Puma 4.3.1 and 3.12.2.
