The go command may execute arbitrary code at build time when cgo is in use. This may occur when running go get on a malicious package, or any other command that builds untrusted code.

This can be caused by a malicious gcc flags specified via a #cgo directive.

Thanks to Imre Rad for reporting this issue.

This issue is CVE-2020-28367.
