Background
The ruby-rack package is a modular Ruby web server interface that facilitates the development of web applications. It provides a simple and consistent API for handling HTTP requests and responses, making it a popular choice among Ruby developers. However, recent vulnerabilities have been identified that could allow remote attackers to exploit the package, leading to potential denial of service (DoS) conditions.
Vulnerability Detail
Multiple vulnerabilities have been discovered in the ruby-rack package. These include improper handling of Multipart MIME parsing (CVE-2023-27530), incorrect parsing of certain media types (CVE-2024-25126), mishandling of Range headers (CVE-2024-26141), and improper handling of crafted headers (CVE-2024-26146).
