Background
Ruby is a dynamic, open-source programming language known for its simplicity and productivity. It is widely used for web development, particularly with the Ruby on Rails framework. The affected packages, including jruby and various ruby versions, are essential for running Ruby applications. This vulnerability exposes these packages to potential exploitation, compromising the integrity and confidentiality of applications that rely on them.
Vulnerability Detail
An issue was discovered in Ruby 3.x through 3.3.0. If attacker-supplied data is provided to the Ruby regex compiler, it is possible to extract arbitrary heap data relative to the start of the text, including pointers and sensitive strings. This vulnerability can lead to unauthorized access to sensitive information, potentially allowing attackers to manipulate or exploit the application further.
