NVD Description

Note: Versions mentioned in the description apply only to the upstream go-toolset-1.15-golang-src package and not the go-toolset-1.15-golang-src package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

Go before 1.15.13 and 1.16.x before 1.16.5 has functions for DNS lookups that do not validate replies from DNS servers, and thus a return value may contain an unsafe injection (e.g., XSS) that does not conform to the RFC1035 format.
