The installed version of Firefox is earlier than 3.0.9. Such versions are potentially affected by the following security issues :

  - Multiple remote memory corruption vulnerabilities exist     that can be exploited to execute arbitrary code in the     context of the user running the affected application.
    (MFSA 2009-14)

  - A flaw may exist where Unicode box drawing characters     are allowed in Internationalized Domain Names where they     could be visually confused with punctuation used in     valid web addresses. An attacker can leverage this to     launch a phishing-type scam against a victim.     (MFSA 2009-15)

  - A vulnerability exists when the 'jar:' scheme is used to     wrap a URI which serves the content with     'Content-Disposition: attachment'. An attacker can     leverage this to subvert sites that use this mechanism     to mitigate content injection attacks. (MFSA 2009-16)   
  - When an Adobe Flash file is loaded via the     'view-source:' scheme, the Flash plugin misinterprets     the origin of the content as localhost. An attacker can     leverage this to launch cross-site request forgery     attacks. It is also possible to exploit this to place     cookie-like objects on victim's computers.
    (MFSA 2009-17)

  - A vulnerability exists that allows attackers to inject     arbitrary scripts into sites via XBL bindings. This     vulnerability requires the attacker to have the ability     to embed third-party stylesheets into the site.     (MFSA 2009-18)

  - Multiple remote code execution vulnerabilities exist     caused by the creation of documents whose URI does not     match the document's principle using XMLHttpRequest, as     well as a flaw in the 'XPCNativeWrapper.ToString'     '__proto__' coming from the wrong scope. (MFSA 2009-19)

  - A malicious MozSearch plugin could be created using a     javascript: URI in the SearchForm value. An attacker can     leverage this in order to inject code into arbitrary     sites. (MFSA 2009-20)

  - An information disclosure vulnerability exists when     saving the inner frame of a web page as a file when the     outer page has POST data associated with it.     (MFSA 2009-21)

  - A cross-site scripting vulnerability exists when     handling a Refresh header containing a javascript: URI.
    (MFSA 2009-22)
