Python ipaddress CVE-2024-4032 incorrect is_private/is_global until v3.12.4
CVE-2024-4032 Published on June 17, 2024

Incorrect IPv4 and IPv6 private ranges
The ipaddress module contained incorrect information about whether certain IPv4 and IPv6 addresses were designated as globally reachable or private. This affected the is_private and is_global properties of the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and ipaddress.IPv6Network classes, where values wouldnt be returned in accordance with the latest information from the IANA Special-Purpose Address Registries. CPython 3.12.4 and 3.13.0a6 contain updated information from these registries and thus have the intended behavior.
