AlmaLinux 9.2 [TuxCare] Security Update: python3.11-urllib3 (ALMALINUX9.2:CLSA-2025:1763032859)

high Nessus Plugin ID 359699

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has a package installed that is affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2025:1763032859 advisory.

- urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user.
However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been patched in urllib3 version 1.26.17 or 2.0.5. (CVE-2023-43804)

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

Solution

Update the affected python3.11-urllib3 package based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2025:1763032859.
