CVE-2021-47154

Publication date 18 March 2024

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
