Package : puma Version : 3.12.0-2+deb10u3 CVE ID : CVE-2021-29509 CVE-2021-41136 CVE-2022-23634 CVE-2022-24790

Multiple security issues have been found in puma, a web server for ruby/rack applications.

CVE-2021-29509

Keepalive Connections Causing Denial Of Service in puma.

CVE-2021-41136

puma with a proxy which forwards HTTP header values which contain the LF character could allow HTTP request smugggling. A client could smuggle a request through a proxy, causing the proxy to send a response back to another unknown client.

CVE-2022-23634

puma may not always call `close` on the response body. Rails, prior to version `7.0.2.2`, depended on the response body being closed in order for its `CurrentAttributes` implementation to work correctly. The combination of these two behaviors (Puma not closing the body + Rails' Executor implementation) causes information leakage.

CVE-2022-24790

using Puma behind a proxy that does not properly validate that the incoming HTTP request matches the RFC7230 standard, Puma and the frontend proxy may disagree on where a request starts and ends.
This would allow requests to be smuggled via the front-end proxy to Puma

For Debian 10 buster, these problems have been fixed in version 3.12.0-2+deb10u3.

We recommend that you upgrade your puma packages.
