rubygem-rack: Possible DoS Vulnerability with Range Header in Rack
A denial of service DoS vulnerability was found in rubygem-rack in how it parses Range Header. Carefully crafted range headers can cause a server to respond with an unexpectedly large response. Responding with large responses could lead to a denial of service issue...
OESA-2024-2032 rubygem-rack security update
Rack provides a minimal, modular, and adaptable interface for developing web applications in Ruby. By wrapping HTTP requests and responses in the simplest way possible, it unifies and distills the API for web servers, web frameworks, and software in between the so-called middleware into a single...

The vulnerability of the modular interface between web servers and web applications in Rack, related to the inefficient complexity of regular expressions, allows attackers to trigger service failures.
The vulnerability of the modular interface between web servers and web applications in Rack relates to the processing of input data, which can take an unexpected amount of time. Exploiting this vulnerability allows a malicious actor to cause service failures...
Denial Of Service (DoS)
Rack is vulnerable to Denial of Service DoS. The vulnerability is due to improper handling of Range headers, allowing an attacker to craft headers in a way that results in an unexpectedly large response, which can result in Denial of Service DoS...
DEBIAN-CVE-2024-26146
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 Ru...
