Debian dla-3800 : ruby-rack - security update

medium Nessus Plugin ID 194449

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-3800 advisory.

- 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)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the ruby-rack packages.
