The go command may execute arbitrary code at build time when using cgo. This may occur when running โ€œgo getโ€ on a malicious module, or when running any other command which builds untrusted code. This is can by triggered by linker flags, specified via a โ€œ#cgo LDFLAGSโ€ directive. Flags containing embedded spaces are mishandled, allowing disallowed flags to be smuggled through the LDFLAGS sanitization by including them in the argument of another flag. This only affects usage of the gccgo compiler.
