		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">perl-Net-CIDR-Lite security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for perl-Net-CIDR-Lite is now available for openEuler-20.03-LTS-SP4.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Faster alternative to Net::CIDR when merging a large number of CIDR address ranges. Works for IPv4 and IPv6 addresses.

Security Fix(es):

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.(CVE-2021-47154)</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for perl-Net-CIDR-Lite is now available for openEuler-20.03-LTS-SP4.
