QID 356170: Amazon Linux Security Advisory for python38 : ALASPYTHON3.8-2023-002

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. (
