Re: [Full-Disclosure] Firefox 0.92 DoS via TinyBMP

["Bernardo Santos Wernesback" <bernardo@xxxxxxxxxx>]

Just tested on Windows XP Professional (fully patched) + IE SP1 and
experienced the same problem.

The first time I opened the page memory usage could be seen on Task
Manager but the machine still responded.

The second time the machine became unresponsive.

Are you certain this is a vuln in Firefox?

On W2K SP4 fully patched: I can verify that opening that page in 
Firefox 0.9.2 causes VM to balloon.

However, I get almost identical results opening the same page in IE 
6sp1, and can cause excessive VM consumption by opening little.bmp 
referenced in your page in MS Paint.
