Re: Malicious documents?

I see that merely by visiting a page with a *really* big font you can
crash your X server (http://www.theregister.co.uk/content/55/25689.html).

Similarly I can hang Mozilla by loading the old "billion laughs"
document (http://www.cogsci.ed.ac.uk/~richard/billion-laughs.xml -
don't try it unless you're willing to restart your browser).

I had to install several checks on my XML checking page
(http://www.cogsci.ed.ac.uk/~richard/xml-check.html), in one case to
prevent it being used to download advertising images for which the
abuser presumably received payment per hit.
