  - Code to sanity-check pathnames on NTFS can result in reading out-of-bounds memory

  - With a crafted .gitmodules file, a malicious project can execute an arbitrary script on a machine that runs
    'git clone --recurse-submodules' because submodule 'names' are obtained from this file, and then appended
    to $GIT_DIR/modules, leading to directory traversal with '../' in a name.
    Finally, post-checkout hooks from a submodule are executed, bypassing the intended design in which hooks
    are not obtained from a remote server (Remote Code Execution can occur)");
