| summary: Improper handling of non-optional LDFLAGS in go command with cgo in cmd/go |
| description: |- |
| The go command may execute arbitrary code at build time when using cgo. This may |
| occur when running "go get" 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 "#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. |
