| Description | Building a malicious package that uses cgo could cause arbitrary code execution at link time by passing linker script files to the host linker via "#cgo LDFLAGS". Split "-Wl," flags that consume a following argument (such as "-Wl,-rpath", "-Wl,--just-symbols", and "-Wl,-undefined") previously accepted a bare second argument without a "-Wl," prefix, which the compiler driver passes directly to the linker as a positional input file. Additionally, when using GNU ld.bfd, flags such as "-framework", "-Wl,-framework", "-Wl,-undefined", "-Wl,--just-symbols", "-Wl,-R", "-Wl,-subsystem", and (on non-Darwin platforms) "-Wl,-sectcreate" could cause ld.bfd to interpret their arguments as linker scripts if they named a regular file on disk. The go command now requires a "-Wl," prefix on the second token of split "-Wl," flags (except "-Wl,-R"), verifies that these flags do not reference linker script files, and disallows bare "-Wl,--warn-backrefs-exclude". | |
