How to fix?

There is no fixed version for Debian:11 golang-1.15.

NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-1.15 package and not the golang-1.15 package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation. This affects net.ParseIP and net.ParseCIDR.
