Summary:
Ubuntu Linux has recently issued security updates addressing vulnerabilities in two key software components: Rack and jq. The updates are detailed in Ubuntu Security Notices USN-7366-2 and USN-7657-2, respectively.
Rack Vulnerabilities (USN-7366-2):
- Release Date: July 23, 2025
- Affected Version: Ubuntu 25.04
- Description: The ruby-rack, a modular Ruby webserver interface, had several vulnerabilities. Notably:
- CRLF injection vulnerability due to improper handling of usernames (CVE-2025-25184).
- Log injection vulnerability due to mishandled headers (CVE-2025-27111).
- Local file inclusion vulnerability from inadequate management of relative file paths (CVE-2025-27610).
- Update Recommendation: Users should ensure they are running ruby-rack version 2.2.7-1.1ubuntu0.25.04.2 or later, which can generally be achieved through a standard system update.
jq Vulnerabilities (USN-7657-2):
- Release Date: July 22, 2025
- Affected Versions: Ubuntu 20.04 LTS, 18.04 LTS, and 16.04 LTS
- Description: The jq tool, a lightweight command-line JSON processor, faced vulnerabilities that could lead to denial of service or arbitrary code execution:
- Denial of service due to improper handling of JSON values (CVE-2024-23337).
- Potential arbitrary code execution from similar JSON handling issues (CVE-2025-48060).
- Update Recommendation: Users should update to the following versions:
- For Ubuntu 20.04 LTS: jq 1.6-1ubuntu0.20.04.1+esm1
- For Ubuntu 18.04 LTS: jq 1.5+dfsg-2ubuntu0.1~esm1
- For Ubuntu 16.04 LTS: jq 1.5+dfsg-1ubuntu0.1+esm3
These updates are available through Ubuntu Pro and can be installed via a standard system update.
Extended Information:
These updates emphasize the importance of maintaining software security, particularly for web applications and command-line tools that handle user input or data parsing. Users are encouraged to regularly check for updates and apply security patches promptly to minimize the risk of exploitation from vulnerabilities. Additionally, organizations should consider implementing automated update solutions and monitoring systems for timely alerts on security issues. Regular security audits and code reviews can further enhance the resilience of applications against such vulnerabilities
