Solutions

Although FortiGates, FortiMail, FortiCache and FortiSwitchOS are vulnerable in their default configuration, there is a CLI setting which disables SSLv3 (see settings details below). As of this writing, the only reported compatibility issue that may ensue is with Internet Explorer 6.
Thus a patch release will not be necessary for FortiGates, all versions (4.3.X, 5.0.X, 5.2.X), FortiMail (5.0.X and 5.2.X), FortiCache, FortiVoice-Enterprise, FortiRecorder and FortiSwitchOS.
The status of other products within the Fortinet family is being reviewed, and this advisory will be updated accordingly.
Alternatively, SSLv3 can be disabled in client browsers (refer to documentation for your browser, or to the FortiGuard FAQ on Poodle - see link in References below).
FortiOS - Apply the settings:
For the HTTPS GUI:

    config system global      set strong-crypto enable      end

For the VIP load-balance:
    config firewall vip       edit "your_vip"      set ssl-min-version tls-1.0      end  
For SSL VPN:
    config vpn ssl settings    set sslv3 disable  (enabled per default)    end
For wanopt:
