Ubuntu Linux has recently rolled out a series of security updates addressing vulnerabilities across various components, including ModSecurity, Python, cifs-utils, Requests, Dojo, Django, and c3p0. These updates are critical for maintaining system integrity and user security.
1. ModSecurity (USN-7567-1): Several vulnerabilities were fixed, including issues with JSON object handling and form data parsing, which could lead to denial of service attacks (CVE-2025-47947, CVE-2025-48866). Updates are available for multiple Ubuntu versions ranging from 14.04 LTS to 25.04.
2. Python (USN-7570-1): Multiple Python versions were found to have vulnerabilities that could lead to crashes or exposure of sensitive information, particularly when handling unicode characters (CVE-2025-4516, CVE-2025-1795). The affected versions include Python 3.6 through 3.13 across various Ubuntu distributions.
3. cifs-utils (USN-7536-2): A regression introduced in a previous update was rectified, ensuring correct handling of namespaces when obtaining Kerberos credentials, preventing potential information leaks.
4. Requests (USN-7568-1): Issues with HTTP header handling that could lead to information leakage were addressed, affecting older Ubuntu releases like 14.04 LTS (CVE-2023-32681, CVE-2024-47081).
5. Dojo (USN-7569-1): Vulnerabilities related to DataGrids and improper input sanitization were resolved, which could allow for cross-site scripting (XSS) and arbitrary code execution in older LTS versions (CVE-2018-15494, CVE-2019-10785).
6. Django (USN-7555-2): A log injection vulnerability was fixed after an incomplete patch was identified. This affects Django versions in Ubuntu 22.04 LTS and earlier.
7. c3p0 (USN-7571-1): A vulnerability in c3p0 could lead to crashes if it opened specially crafted files, affecting Ubuntu 14.04 LTS.
For all affected packages, users are encouraged to perform a standard system update to ensure they have the latest security patches. Specific package versions to update to for various Ubuntu releases are detailed in the advisory notices.
These updates highlight the importance of maintaining current software versions to safeguard against potential vulnerabilities. Users should prioritize updating their systems, especially if they are running older versions of Ubuntu that may be more susceptible to attacks. The Ubuntu Security Notices provide comprehensive details and guidance on how to address these vulnerabilities effectively.
