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
The advisory covers two vulnerabilities in Python 3.12 on Red Hat Enterprise Linux 9. CVE-2026-6100 is a use-after-free vulnerability in decompression modules that could lead to arbitrary code execution or information disclosure. CVE-2026-4786 is a command injection vulnerability in the webbrowser.open() API that could also allow arbitrary code execution. These vulnerabilities affect multiple Red Hat Enterprise Linux 9 variants and architectures including x86_64, s390x, ppc64le, and aarch64. Red Hat has issued updated python3.12 packages to remediate these issues.
Potential Impact
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary code or disclose sensitive information on affected systems running vulnerable Python 3.12 versions. This could compromise system integrity and confidentiality. However, there are no known exploits in the wild currently.
Mitigation Recommendations
Red Hat has released updated python3.12 packages for Red Hat Enterprise Linux 9 and related variants that address these vulnerabilities. Users should apply these official updates promptly to remediate the issues. For detailed update instructions, refer to Red Hat's advisory and article at https://access.redhat.com/articles/11258. Patch status is confirmed as fixed by Red Hat.
