CVE-2024-4032

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.

A flaw was found in Python. The ipaddress module contained incorrect information about whether certain IPv4 and IPv6 addresses were designated as “globally reachable” or “private”. Due to this issue, it is possible that values will not be returned in accordance with the latest information from the IANA Special-Purpose Address Registries.

It was discovered that the Python ipaddress module contained incorrect information about which IP address ranges were considered “private” or “globally reachable”. This could possibly result in applications applying incorrect security policies. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. It was discovered that Python incorrectly handled quoting path names when using the venv module. A local attacker able to control virtual environments could possibly use this issue to execute arbitrary code when the virtual environment is activated.
