The installed version of Firefox is earlier than 3.0.11. Such versions are potentially affected by the following security issues :

  - Multiple memory corruption vulnerabilities could     potentially be exploited to execute arbitrary code.     (MFSA 2009-24)

  - Certain invalid Unicode characters, when used as a part     of IDN, can be displayed as a whitespace in the location     bar. An attacker could exploit this vulnerability to     spoof the location bar. (MFSA 2009-25)  

  - It may be possible for local resources loaded via     'file:' protocol to access any domain's cookies saved     on a user's system. (MFSA 2009-26)

  - It may be possible to tamper with SSL data via non-200     responses to proxy CONNECT requests. (MFSA 2009-27)

  - A race condition exists in 'NPObjWrapper_NewResolve'     when accessing the properties of a NPObject, a     wrapped JSObject. This flaw could be potentially     exploited to execute arbitrary code on the remote     system. (MFSA 2009-28)

  - If the owner document of an element becomes null after     garbage collection, then it may be possible to execute     the event listeners within the wrong JavaScript context.
    An attacker could potentially exploit this vulnerability     to execute arbitrary JavaScript with chrome privileges.
    (MFSA 2009-29)  

  - When the 'file:' resource is loaded from the location     bar, the resource inherits the principal of the     previously loaded document. This could potentially allow     unauthorized access to local files. (MFSA 2009-30)

  - While loading external scripts into XUL documents     content-loading policies are not checked.     (MFSA 2009-31)   

  - It may be possible for scripts from page content to     run with elevated privileges. (MFSA 2009-32)
