Oracle Linux: CVE-2024-3651: ELSA-2024-3466: python39:3.9 and python39-devel:3.9 security update (IMPORTANT) (Multiple Advisories)

A vulnerability was identified in the kjd/idna library, specifically within the `idna.encode()` function, affecting version 3.6. The issue arises from the function's handling of crafted input strings, which can lead to quadratic complexity and consequently, a denial of service condition. This vulnerability is triggered by a crafted input that causes the `idna.encode()` function to process the input with considerable computational load, significantly increasing the processing time in a quadratic manner relative to the input size.
A flaw was found in the python-idna library. A malicious argument was sent to the idna.encode() function can trigger an uncontrolled resource consumption, resulting in a denial of service.
