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.

   This issue is described in the following documents:

   http://www.mozilla.org/security/announce/2006/mfsa2006-68.html
