Descriptions

The Net::CIDR::Lite module before 0.22 for Perl does not properly consider extraneous zero characters at the beginning of an IP address string, which (in some situations) allows attackers to bypass access control that is based on IP addresses.

El módulo Net::CIDR::Lite anterior a 0.22 para Perl no considera adecuadamente los caracteres cero extraños al comienzo de una cadena de dirección IP, lo que (en algunas situaciones) permite a los atacantes eludir el control de acceso basado en direcciones IP.
