1. Impact
A security vulnerability in the Mozilla (see mozilla(1)) js_dtoa()
function may cause the Mozilla application to crash if a user views a
web page, mail message, or newsgroup message when certain plugins are
installed. The ability of a remote user who creates such a web page,
mail message, or newsgroup post to cause the Mozilla application to
crash is a type of Denial of Service.
