"lang": "en",

"value": "When using GCC, building a malicious package that uses cgo could cause arbitrary command execution at link time via untrusted GCC spec files (\"specs\" or \"*.spec\"). When linking with \"-fopenmp\", \"-fopenacc\", or \"-fsanitize=\" in \"#cgo LDFLAGS\", GCC's built-in link spec evaluates \"%:include(libgomp.spec)\" or \"%:include(libsanitizer.spec)\" and searches for spec files in \"-L\" and sysroot directories (including subdirectories and multilib sibling directories such as \"../lib64\"), as well as the working directory when \"-fopenmp\" or \"-fopenacc\" is used or when \"-fsanitize=\" is combined with \"-static\" or \"-static-lib*\". The go command now rejects \"-L\", \"-isysroot\", and \"-Wl,-syslibroot\" directories (and the working and package directories when applicable) that contain GCC spec files, and disallows \"@\" and \"-\" prefixes in \"-fsanitize=\" compiler flag values."
