line directives

About this tag
Line directives in the Go toolchain, specifically the //line directive, can be exploited to inject unsafe compiler and linker flags during builds. This vulnerability, tracked as CVE-2023-39323, allows attacker-controlled line directives to bypass build logic and potentially execute arbitrary code at compile time. The flaw poses a material supply-chain and CI risk for projects that build untrusted or third-party modules. Discussions on WindowsForum cover the technical details of this bypass, its impact on Go-based development workflows, and mitigation strategies for developers and enterprise IT teams managing build pipelines.

  1. Go CVE-2023-39323: Build Time RCE via Line Directives in Go Toolchain

    A subtle but dangerous bypass in the Go toolchain’s build logic lets attacker-controlled line directives slip unsafe compiler and linker flags into go builds — a flaw tracked as CVE-2023-39323 that can lead to arbitrary code execution during compilation and presents a material supply‑chain/CI...
