Important: python security update (Amazon Linux 2)

Published Mar 2, 2023 · Updated Mar 7, 2023

Summary

Package updates are available for Amazon Linux 2 that fix the following vulnerabilities: CVE-2023-24329: An issue in the urllib.parse component of Python before v3.11 allows attackers to bypass blocklisting methods by supplying a URL that starts with blank characters. CVE-2022-45061: An issue was discovered in Python before 3.11.1. An unnecessary quadratic algorithm exists in one path when processing some inputs to the IDNA (RFC 3490) decoder, such that a crafted, unreasonably long name being presented to the decoder could lead to a CPU denial of service. Hostnames are often supplied by remote servers that could be controlled by a malicious actor; in such a scenario, they could trigger excessive CPU consumption on the client attempting to make use of an attacker-supplied supposed hostname. For example, the attack payload could be placed in the Location header of an HTTP response with status code 302. A fix is planned in 3.11.1, 3.10.9, 3.9.16, 3.8.16, and 3.7.16.
