    I've downloaded this fixed version, but it seems to be vulnerable to
    something I've discovered last week: if you take a .swf and rot13 encode
    it (not all of it, so the headers are not messed up), you can crash the
    user's browser. I've tested it on Netscape 4.77 with Flash 4.0 r12 and
    Galeon 1.2.5, which is based on Mozilla 1.0, with Flash 5.0 r50 (both
    running on Debian unstable) and IE 6.0 (on Windows 2000) and all of them
    crash instantly when I try to open the rot13-garbled file.

    Check it out:
