Amazon Linux AMI : python38 (ALAS-2024-1936)

high Nessus Plugin ID 196929

Language:

Synopsis

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

Description

The version of python38 installed on the remote host is prior to 3.8.5-1.11. It is, therefore, affected by a vulnerability as referenced in the ALAS-2024-1936 advisory.

 - An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7, 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)

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 python38' to update your system.
