Mozilla Thunderbird < 2.0.0.16 Multiple Vulnerabilities

High

Synopsis

The remote Windows host contains a mail client that is affected by multiple vulnerabilities.

Description

The installed version of Thunderbird is affected by various security issues :

- Several stability bugs leading to crashes that, in some cases, show traces of memory corruption (MFSA 2008-21).

- By taking advantage of the privilege level stored in the pre-compiled 'fastload' file, an attacker may be able to run arbitrary JavaScript code with chrome privileges (MFSA 2008-24).

- Arbitrary code execution is possible in 'mozIJSSubScriptLoader.loadSubScript()' (MFSA 2008-25).

- Several function calls in the MIME handling code use unsafe versions of string routines (MFSA 2008-26).

- An improperly encoded '.properties' file in an add-on can result in uninitialized memory being used, which could lead to data formerly used by other programs being exposed to the add-on code (MFSA 2008-29).

- A weakness in the trust model regarding alt names on peer-trusted certs could lead to spoofing secure connections to any other site (MFSA 2008-31).

- A crash in Mozilla's block reflow code could be used by an attacker to crash the browser and run arbitrary code on the victim's computer (MFSA 2008-33).

- By creating a very large number of references to a common CSS object, an attacker can overflow the CSS reference counter, causing a crash when the browser attempts to free the CSS object while still in use and allowing for arbitrary code execution (MFSA 2008-34).

Solution

Upgrade to version 2.0.0.16 or higher.
