Fixed In Version: go 1.20.5, go 1.19.10
Doc Type: If docs needed, set a value
Doc Text:
A flaw was found in golang. The go command may execute arbitrary code at build time when using cgo. This can occur when running "go get" on a malicious module, or when running any other command which builds untrusted code. This can be triggered by linker flags, specified via a "#cgo LDFLAGS" directive. The arguments for a number of flags which are non-optional are incorrectly considered optional, allowing disallowed flags to be smuggled through the LDFLAGS sanitization. This affects usage of both the gc and gccgo compilers.
