Various uses of the Go toolchain in untrusted VCS repositories can result in unexpected code execution. When using the Go toolchain in directories fetched using various VCS tools (such as directly cloning Git or Mercurial repositories) can cause the toolchain to execute unexpected commands, if said directory contains multiple VCS configuration metadata (such as a '.hg' directory in a Git repository). This is due to how the Go toolchain attempts to resolve which VCS is being used in order to embed build information in binaries and determine module versions.
