"value": "Building a malicious package that uses \"#cgo pkg-config:\" directives could load untrusted pkg-config \".pc\" files or inject unvalidated compiler and linker flags. The pkg-config flag allowlist previously permitted \"--with-path=\" and \"--personality=\", allowed \"--define-variable=\" values beginning with \"=\" or \"$\" (which can rewrite paths in system \".pc\" files into sysroot-prefixed \"-L=\" or \"-L$SYSROOT\" linker search paths), and allowed package arguments ending in \".pc\" or containing path separators or \"..\", which caused pkg-config to load local \".pc\" files directly from the package directory. In addition, flags returned by \"pkg-config --cflags\" in cgoCPPFLAGS were not checked when determining whether internal linking is safe. The go command now disallows \"--with-path=\", \"--personality=\", leading \"=\" or \"$\" characters in \"--define-variable=\" values, and local \".pc\" paths in \"#cgo pkg-config:\" directives, and inspects cgoCPPFLAGS when checking internal linking compatibility."
