Not to mention all the other crazy stuff that you can do with an archive.
You can create a file full of zeros, so that the .tar.gz is only a few
KB big, but when unpacked it's terabytes large and try to ruin the
users machine that way.
Or make the unpacked file small, but have holes in it so that when
it's read it's terabytes large.
