| summary: |- |
| Improper sanitization of LDFLAGS with embedded spaces 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. |
| |
| 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. |
