One issue with all this is that the GNU tools are vastly superior
to older ones (in terms of extra functionality) but most people
never have the misfortune to have to use other unix systems that
don't have them.
Imagine tar without the 'z' option, find with only 'name' as a predicate,
and so on.
Buffer overflows also happen when you use a single char with
"%[...]" in scanf; this inputs as many chars as it can match,
and null-terminates the string.
Even when they aren't able to be exploited (i.e. not in a
program with special uid), buffer overflows can make
