CVE-2024-24787

Arbitrary code execution via linker library loading

Published May 8, 2024 · Updated Feb 13, 2025

Command injection in Google Cloud Go command before 1.21.10 and 1.22.0 through 1.22.2 allows attackers to execute code during macOS builds. cmd/go accepts an attacker-controlled -lto_library argument from a #cgo LDFLAGS directive and passes it to Apple ld, which loads and executes the named library. Exploitation requires a user with CGO enabled to build the crafted module on Darwin; code runs with that user's build privileges.
