Firefox < 3.0.11 Multiple Vulnerabilities

Synopsis :

The remote Windows host contains a web browser that is affected by
multiple vulnerabilities.

Description :

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)
