The Python standard library ipaddress also suffers from the critical IP address validation vulnerability identical to the flaw that was reported in the “netmask”” library earlier this year. The bug concerns improper parsing of IP addresses by the ipaddress standard library. Python’s ipaddress module allows unauthenticated remote attackers to perform indeterminicated attacks on many programs that rely on the module. The vulnerability is tracked as CVE-2021-29921
