How to fix?

There is no fixed version for Centos:6 perl-core.

NVD Description

Note: Versions mentioned in the description apply only to the upstream perl-core package and not the perl-core package as distributed by Centos. See How to fix? for Centos:6 relevant fixed versions and status.

Net::CIDR::Lite versions before 0.24 for Perl does not properly validate IP address and CIDR mask inputs, which may allow IP ACL bypass.

Inputs containing a trailing newline or non-ASCII digit characters pass the validators but are then re-encoded by the parser to a different address than the input string spelled. find() and bin_find() can match or miss addresses as a result.

Example:

my $cidr = Net::CIDR::Lite->new(); $cidr->add("::1\n/128"); $cidr->find("::1a"); # incorrectly returns true
