About this tag
The cgo security tag on WindowsForum.com covers vulnerabilities and risks related to Go's cgo mechanism, particularly focusing on build-time code execution threats. A key topic is CVE-2023-29405, a parsing bug in Go's build tooling that allows improper sanitization of LDFLAGS with embedded spaces when cgo is enabled. This flaw enables attackers to smuggle disallowed linker flags, leading to arbitrary code execution during compilation. The issue is a supply-chain problem, exploitable via malicious modules or dependencies with crafted #cgo LDFLAGS. Discussions emphasize the importance of securing build pipelines and validating cgo flags to prevent such attacks.

    Go cgo LDFLAGS Bug CVE-2023-29405: Build Time Code Execution Risk

    A subtle parsing bug in Go’s build tooling quietly opened a door for attackers to run code during compilation — and the fallout is wider than you might expect if your environment uses gccgo or builds untrusted modules. CVE-2023-29405 exposes an improper sanitization of LDFLAGS with embedded...
