Firefox 3.0.x < 3.0.2 Multiple Vulnerabilities

This script is Copyright (C) 2008-2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

The installed version of Firefox 3.0 is earlier than 3.0.2. Such
versions are potentially affected by the following security issues :

- An attacker can cause the content window to move while
the mouse is being clicked, causing an item to be
dragged rather than clicked-on (MFSA 2008-40).

- Privilege escalation is possible via 'XPCnativeWrapper'
pollution (MFSA 2008-41).

- There are several stability bugs in the browser engine
that could lead to crashes with evidence of memory
corruption (MFSA 2008-42).

- Certain BOM characters and low surrogate characters,
if HTML-escaped, are stripped from JavaScript code
before it is executed, which could allow for cross-
site scripting attacks (MFSA 2008-43).

- The 'resource:' protocol allows directory traversal
on Linux when using URL-encoded slashes, and it can
by used to bypass restrictions on local HTML files
(MFSA 2008-44).

- By tampering with the window.__proto__.__proto__ object,
one can cause the browser to place a lock on a non-
native object, leading to a crash and possible code
execution. (MFSA 2008-50)
