Hi,
The following vulnerability was published for puma.
CVE-2024-21647[0]:
| Puma is a web server for Ruby/Rack applications built for
| parallelism. Prior to version 6.4.2, puma exhibited incorrect
| behavior when parsing chunked transfer encoding bodies in a way that
| allowed HTTP request smuggling. Fixed versions limits the size of
| chunk extensions. Without this limit, an attacker could cause
| unbounded resource (CPU, network bandwidth) consumption. This
| vulnerability has been fixed in versions 6.4.2 and 5.6.8.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
