Fedora 33: 2021-d0cc9a393f Critical: Prevent IP Leading Zeroes

fedora
Calendar Grey April 13, 2021
Dist Fedora Esm H88
Significant Debian patch blocks IP addresses containing leading zeroes to eliminate misinterpretation issues.
This update disallows use of IP addresses with leading zeroes in the octet values, which could have been interpreted ambiguously as either octal or decimal values.

Summary

Faster alternative to Net::CIDR when merging a large number of CIDR address

ranges. Works for IPv4 and IPv6 addresses.

This update disallows use of IP addresses with leading zeroes in the octet

values, which could have been interpreted ambiguously as either octal or decimal

values.
