    Summary: Updated perl-Net-CIDR-Lite package fixes a security vulnerability

    Details: It was discovered that the perl Net-CIDR-Lite module did not correctly handle IP addresses with IP octets containing leading zeros. Leading zeros were ignored, while the underlying system can treat such octets as octal numbers and interpret them differently. For example, IP address of 010.0.0.1 was considered by Net CIDR-Lite to be the same address as 10.0.0.1, while system may consider it to be IP address 8.0.0.1 (rhbz# 1961865).
