Amazon Linux 2022 : python3.10 (ALAS2022-2022-212)

high Nessus Plugin ID 168578

Language:

Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

The version of python3.10 installed on the remote host is prior to 3.10.8-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-212 advisory.

 - A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int(text), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability. (CVE-2020-10735)

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 python3.10' to update your system.
