Background
Ruby is a dynamic, open-source programming language known for its simplicity and productivity. It supports multiple programming paradigms, including functional and object-oriented programming. The affected packages, ruby2.5, ruby2.7, ruby3.0, ruby3.2, and ruby3.3, are essential for running Ruby applications on Ubuntu systems. These packages provide the Ruby interpreter and development tools necessary for building and executing Ruby programs. However, recent vulnerabilities have been discovered that could compromise the security and stability of applications relying on these versions.
Vulnerability Detail
The vulnerabilities stem from improper handling of IO stream methods, memory operations, XML character parsing, and decompressed domain names within DNS packets. These issues could allow remote attackers to crash Ruby applications, leading to denial of service, or potentially expose sensitive information. Specifically, CVE-2024-27280 and CVE-2024-27282 affect Ruby's handling of IO streams and memory, while CVE-2024-35176 and CVE-2025-24294 relate to XML parsing and DNS packet handling, respectively. Notably, these vulnerabilities primarily impact Ubuntu 18.04 LTS.
