Red Hat Security Advisory: python3.11 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 covers two security flaws in python3.11 on Red Hat Enterprise Linux 9.2. CVE-2026-6100 is a use-after-free vulnerability in decompression modules that can result in arbitrary code execution or information disclosure. CVE-2026-4786 is a command injection vulnerability in the webbrowser.open() API that enables arbitrary code execution. Both vulnerabilities are addressed by updated python3.11 packages provided by Red Hat. The advisory references Red Hat's errata RHSA-2026:13692 for detailed remediation instructions.
Potential Impact
Successful exploitation of CVE-2026-6100 could allow an attacker to execute arbitrary code or disclose sensitive information due to a use-after-free condition in decompression modules. CVE-2026-4786 could enable arbitrary code execution through command injection in the webbrowser.open() API. These vulnerabilities pose a high security risk on affected systems running vulnerable python3.11 versions, potentially compromising system integrity and confidentiality.
Mitigation Recommendations
Red Hat has released updated python3.11 packages that fix these vulnerabilities. Users of Red Hat Enterprise Linux 9.2 and related affected products should apply the security update as detailed in Red Hat advisory RHSA-2026:13692. Patch status is confirmed as fixed by the vendor. No additional mitigation steps are indicated beyond applying the official update.
