NVDhttps://nvd.nist.gov/vuln/detail/CVE-2020-10735
CWEhttps://cwe.mitre.org/data/definitions/704.html

A flaw was found in python. In algorithms with quadratic time complexity using non-binary bases, when using int(text), a system could take 50ms to parse an int string with 100,000 digits and 5s for 1,000,000 digits (float, decimal, int.from_bytes(), and int() for binary bases 2, 4, 8, 16, and 32 are not affected). The highest threat from this vulnerability is to system availability.

Weakness

The product does not correctly convert an object, resource, or structure from one type to a different type.
