Vulnerabilidad en CPython (CVE-2024-4032)
Gravedad CVSS v3.1:
ALTA

Descripción
El módulo "ipaddress" contenía información incorrecta sobre si ciertas direcciones IPv4 e IPv6 estaban designadas como "accesibles globalmente" o "privadas". Esto afectó las propiedades is_private e is_global de las clases ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address y ipaddress.IPv6Network, donde los valores no se devolverían de acuerdo con la información más reciente de los Registros de direcciones de propósito especial de la IANA. CPython 3.12.4 y 3.13.0a6 contienen información actualizada de estos registros y, por lo tanto, tienen el comportamiento previsto.
Impacto
Puntuación base 3.x
