"value": "Building a malicious package containing \"//go:cgo_*\" compiler directives could inject arbitrary flags into the external linker invocation on ELF platforms. The compiler and linker did not reject commas in \"//go:cgo_import_dynamic\", \"//go:cgo_export_dynamic\", \"//go:cgo_export_static\", \"//go:cgo_import_static\", and \"//go:cgo_dynamic_linker\" directives, and the linker passed the dynamic linker path using \"-Wl,--dynamic-linker,<path>\". Furthermore, the two-argument form of \"//go:cgo_import_dynamic\" (which is permitted in non-cgo Go source files) could overwrite the external symbol name of a symbol already marked for cgo export. A symbol name or dynamic linker path containing a comma or leading \"@\" could split \"-Wl,--export-dynamic-symbol=\" or \"-Wl,--dynamic-linker,\" into arbitrary host linker flags or response file arguments. The compiler and linker now reject commas in \"//go:cgo_*\" symbol and dynamic linker directives, the linker passes \"-Wl,--dynamic-linker=<path>\", and \"cgo_import_dynamic\" no longer overwrites symbols exported via \"cgo_export_dynamic\" or \"cgo_export_static\"."
