Rack is a modular Ruby web server interface. Carefully crafted content type headers can cause Rack’s media type parser to take much longer than expected, leading to a possible denial of service vulnerability (ReDos 2nd degree polynomial). This vulnerability is patched in 3.0.9.1 and 2.2.8.1.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7036-1 advisory.

    It was discovered that Rack was not properly parsing data when processing multipart POST requests. If a     user or automated system were tricked into sending a specially crafted multipart POST request to an     application using Rack, a remote attacker could possibly use this issue to cause a denial of service.
    (CVE-2022-30122)

    It was discovered that Rack was not properly escaping untrusted data when performing logging operations,     which could cause shell escaped sequences to be written to a terminal. If a user or automated system were     tricked into sending a specially crafted request to an application using Rack, a remote attacker could     possibly use this issue to execute arbitrary code in the machine running the application. (CVE-2022-30123)

    It was discovered that Rack did not properly structure regular expressions in some of its parsing     components, which could result in uncontrolled resource consumption if an application using Rack received     specially crafted input.

  - Rack is a modular Ruby web server interface. Carefully crafted content type headers can cause Rack's media     type parser to take much longer than expected, leading to a possible denial of service vulnerability     (ReDos 2nd degree polynomial). This vulnerability is patched in 3.0.9.1 and 2.2.8.1. (CVE-2024-25126)

  - Rack is a modular Ruby web server interface. Carefully crafted Range headers can cause a server to respond     with an unexpectedly large response. Responding with such large responses could lead to a denial of     service issue. Vulnerable applications will use the `Rack::File` middleware or the     `Rack::Utils.byte_ranges` methods (this includes Rails applications). The vulnerability is fixed in     3.0.9.1 and 2.2.8.1. (CVE-2024-26141)

  - Rack is a modular Ruby web server interface. Carefully crafted headers can cause header parsing in Rack to     take longer than expected resulting in a possible denial of service issue. Accept and Forwarded headers     are impacted. Ruby 3.2 has mitigations for this problem, so Rack applications using Ruby 3.2 or newer are     unaffected. This vulnerability is fixed in 2.0.9.4, 2.1.4.4, 2.2.8.1, and 3.0.9.1. (CVE-2024-26146)
