AlmaLinux 9.6 [TuxCare] Security Update: python-unversioned-command / python3 / python3-debug / etc Multiple Vulnerabilities (ALMALINUX9.6:CLSA-2026:1780481964)

medium Nessus Plugin ID 360891

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1780481964 advisory.

- The import hook in CPython that handles legacy *.pyc files (SourcelessFileLoader) is incorrectly handled in FileLoader (a base class) and so does not use io.open_code() to read the .pyc files. sys.audit handlers for this audit event therefore do not fire. (CVE-2026-2297)

- http.cookies.Morsel.js_output() returns an inline <script> snippet and only escapes for JavaScript string context. It does not neutralize the HTML parser-sensitive sequence </script> inside the generated script element. Mitigation base64-encodes the cookie value to disallow escaping using cookie value.
(CVE-2026-6019)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.6:CLSA-2026:1780481964.
