| Description | 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. | |
