Wildcard certificate spoofs web authentication
SSL felled by null string

  The attack [...] exploits a weakness in the process for generating secure
  sockets layer certificates. It works by adding a null string character
  to several certificate fields, a technique that tricks browsers and
  other SSL-enabled programs into misinterpreting the domain name that
  is being authenticated.

  ...

  At the moment, version 3.5 of Firefox is the only browser that is
  protected against the attack, although Sassaman said Internet Explorer
  provides some protection too.


FWIW, Firefox 3.5 is available in Ubuntu 9.04 as the "firefox-3.5" package.
(The plain "firefox" package currently gives you Firefox 3.0.12.)
