Quadratic complexity parsing cookies with backslashes (CVE-2024-7592)

Résumé

Quadratic complexity parsing cookies with backslashes

Description d'origine

La description telle que publiée par la source (souvent en anglais).

There is a LOW severity vulnerability affecting CPython, specifically the
'http.cookies' standard library module.

When parsing cookies that contained backslashes for quoted characters in
the cookie value, the parser would use an algorithm with quadratic
complexity, resulting in excess CPU resources being used while parsing the
value.
