Amazon Linux 2 : python3 (ALAS-2024-2515)

medium Nessus Plugin ID 193529

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 ALAS2-2024-2515 advisory.

 - An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The zipfile module is vulnerable to quoted-overlap zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive. (CVE-2024-0450)

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.
