Amazon Linux 2 : python3 (ALAS-2025-2754)

medium Nessus Plugin ID 216814

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 multiple vulnerabilities as referenced in the ALAS2-2025-2754 advisory.

The urllib.parse.urlsplit() and urlparse() functions improperly validated bracketed hosts (`[]`), allowing hosts that weren't IPv6 or IPvFuture. This behavior was not conformant to RFC 3986 and potentially enabled SSRF if a URL is processed by more than one URL parser. (CVE-2024-11168)

There is a MEDIUM severity vulnerability affecting CPython.

Theemail module didn't properly quote newlines for email headers whenserializing an email message allowing for header injection when an emailis serialized. (CVE-2024-6923)

There is a LOW severity vulnerability affecting CPython, specifically the'http.cookies' standard library module.

When parsing cookies that contained backslashes for quoted characters inthe cookie value, the parser would use an algorithm with quadraticcomplexity, resulting in excess CPU resources being used while parsing thevalue. (CVE-2024-7592)

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

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

Solution

Run 'yum update python3' to update your system.
