    The bug affects only in memory modified file data.

    In memory modifications to the file can be deleted
    and the file data reverts to a state before the
    file modification. (Not unlike a crash/power failure )

    The worst security scenario I can think of is the possibility
    to revert a file to uninitialized disk data blocks or to
    prevent the update of a file.
