Red Hat Security Advisory: python3.12 security update
Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. Security Fix(es): * python: Python: Arbitrary code execution or information disclosure via use-after-free in decompression modules (CVE-2026-6100) * python: cpython: Python: Arbitrary code execution via command injection in webbrowser.open() API (CVE-2026-4786) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
This advisory addresses two security vulnerabilities in Python 3.12 as packaged in Red Hat Enterprise Linux 9. CVE-2026-6100 is a use-after-free vulnerability in decompression modules that may allow arbitrary code execution or information disclosure. CVE-2026-4786 is a command injection vulnerability in the webbrowser.open() API that could lead to arbitrary code execution. Red Hat has released updated python3.12 packages to fix these issues. The advisory references Red Hat's errata RHSA-2026:10745 for detailed remediation instructions.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code or disclose sensitive information on affected systems running vulnerable versions of python3.12. This poses a significant security risk, especially for systems that run untrusted Python code or expose the webbrowser.open() API functionality.
Mitigation Recommendations
Red Hat has released updated python3.12 packages for Red Hat Enterprise Linux 9 that address these vulnerabilities. Users should apply the available security update as described in the Red Hat advisory RHSA-2026:10745 and the referenced article https://access.redhat.com/articles/11258 to remediate these issues. No additional mitigations are specified by the vendor.
