summary: Arbitrary code execution in go command with cgo in cmd/go and cmd/cgo
description: |-
    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 malicious unquoted symbol name in a linked object file.

    cwe: 'CWE-94: Improper Control of Generation of Code (''Code Injection'')'
    description: |-
        Code injection in the go command with cgo before Go 1.14.12 and Go 1.15.5 allows
        arbitrary code execution at build time via a malicious unquoted symbol name in a
        linked object file.
