Amazon Linux 2 : python3 (ALAS-2024-2541)

high Nessus Plugin ID 197105

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of python3 installed on the remote host is prior to 3.7.16-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2541 advisory.

 An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.2, 3.11.8, 3.10.13, 3.9.18, and 3.8.18 and prior.

 The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means users which can run privileged programs are potentially able to modify permissions of files referenced by symlinks in some circumstances. (CVE-2023-6597)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

Solution

Run 'yum update python3' to update your system.
