Amazon Linux 2 : python (ALAS-2024-2686)

high Nessus Plugin ID 210096

Language:

Synopsis

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

Description

The version of python installed on the remote host is prior to 2.7.18-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2686 advisory.

The email module of Python through 3.11.3 incorrectly parses e-mail addresses that contain a special character. The wrong portion of an RFC2822 header is identified as the value of the addr-spec. In some applications, an attacker can bypass a protection mechanism in which application access is granted only after verifying receipt of e-mail to a specific domain (e.g., only @company.example.com addresses may be used for signup). This occurs in email/_parseaddr.py in recent versions of Python. (CVE-2023-27043)

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 python' to update your system.
