Description

Net::CIDR::Set versions through 0.20 for Perl did not validate network masks.<br /> <br /> The mask portion of a network mask could contain Unicode digits such as the Arabic-Indic One (U+0661), or non-digits, which were ignored. This could allow network masks to accept larger networks.<br /> <br /> Leading zeros were also accepted, but treated as decimal instead of octal. This could lead to confusion about what networks are acceptable.
