Upgrade AlmaLinux:9 python3 to version 0:3.9.14-1.el9_1.2 or higher.
This issue was patched in ALSA-2023:0953.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python3 package and not the python3 package as distributed by AlmaLinux.
See How to fix? for AlmaLinux:9 relevant fixed versions and status.
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.
