The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6682-1 advisory.

  - In Puma (RubyGem) before 4.3.4 and 3.12.5, an attacker could smuggle an HTTP response, by using an invalid     transfer-encoding header. The problem has been fixed in Puma 3.12.5 and Puma 4.3.4. (CVE-2020-11076)

  - In Puma (RubyGem) before 4.3.5 and 3.12.6, a client could smuggle a request through a proxy, causing the     proxy to send a response back to another unknown client. If the proxy uses persistent connections and the     client adds another request in via HTTP pipelining, the proxy may mistake it as the first request's body.
    Puma, however, would see it as two requests, and when processing the second request, send back a response     that the proxy does not expect. If the proxy has reused the persistent connection to Puma to send another     request for a different client, the second response from the first client will be sent to the second     client. This is a similar but different vulnerability from CVE-2020-11076. The problem has been fixed in     Puma 3.12.6 and Puma 4.3.5. (CVE-2020-11077)

  - Puma is a Ruby/Rack web server built for parallelism. Prior to `puma` version `5.6.2`, `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. This problem is fixed in Puma versions 5.6.2 and 4.3.11. This problem is fixed in Rails versions     7.02.2, 6.1.4.6, 6.0.4.6, and 5.2.6.2. Upgrading to a patched Rails _or_ Puma version fixes the     vulnerability. (CVE-2022-23634)

  - Puma is a simple, fast, multi-threaded, parallel HTTP 1.1 server for Ruby/Rack applications. When 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. The vulnerability has been fixed in 5.6.4 and     4.3.12. Users are advised to upgrade as soon as possible. Workaround: when deploying a proxy in front of     Puma, turning on any and all functionality to make sure that the request matches the RFC7230 standard.
    (CVE-2022-24790)

  - Puma is a Ruby/Rack web server built for parallelism. Prior to versions 6.3.1 and 5.6.7, puma exhibited     incorrect behavior when parsing chunked transfer encoding bodies and zero-length Content-Length headers in     a way that allowed HTTP request smuggling. Severity of this issue is highly dependent on the nature of the     web site using puma is. This could be caused by either incorrect parsing of trailing fields in chunked     transfer encoding bodies or by parsing of blank/zero-length Content-Length headers. Both issues have been     addressed and this vulnerability has been fixed in versions 6.3.1 and 5.6.7. Users are advised to upgrade.
    There are no known workarounds for this vulnerability. (CVE-2023-40175)

  - 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. (CVE-2024-21647)
