Azure Linux 3.0 Security Update: python-urllib3 / python3 (CVE-2023-43804)

critical Nessus Plugin ID 215592

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of python-urllib3 / python3 installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-43804 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 packages.
