The Net::Netmask module before 2.0000 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.

seth-arnold blog.urth.org reports many perl modules affected; I don’t know if this CVE number applies to something else entirely, all of them, or just one of these packages.
