For more information: SA21903 2) An error exists within the handling of Script objects. This can be potentially be exploited to execute arbitrary JavaScript bytecode by modifying already running Script objects. Successful exploitation requires that JavaScript is enabled. 3) Some unspecified errors in the layout engine and memory corruption errors in the JavaScript engine can be exploited to crash the application and may allow the execution of arbitrary code. Successful exploitation of some of these vulnerabilities requires that JavaScript is enabled. 4) An unspecified error within XML.prototype.hasOwnProperty can potentially be exploited to execute arbitrary code. SOLUTION: Update to Mozilla Thunderbird 1.5.0.8.
