A potentially nasty vulnerability in the Git
distributed revision-control system was disclosed on March 9. There are enough
qualifiers in the description of the vulnerability that it may appear to be
fairly narrowly focused—and it is. That may make it less worrisome, but
it is not entirely clear. As with most vulnerabilities, it all depends on how
the software is being used and the environment in which it is running.
