    Improper sanitization when resolving values from DNS in net

    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.

    Panic on certain certificates in crypto/tls
