Who is Vulnerable?
Vulnerability Description Mozilla Firefox is a very popular web browser developed by the Mozilla Foundation. The browser is capable of interpreting and rendering many types of content published on the Internet, including various versions HTML, XML, XUL, JavaScript, various graphics formats, and so on. The browser runs on the Windows, Macintosh, Unix and Linux based platforms. There exists vulnerability in Mozilla Firefox. The vulnerability is due to insufficient validation when handling XUL frame tree. A remote attacker can exploit this vulnerability by enticing the target user to open a crafted web page. Successful exploitation would allow for arbitrary code injection and execution with the privileges of the currently logged on user. In a successful attack, arbitrary code is supplied and executed on the vulnerable target host. The behaviour of the target system is dependent on the malicious code. Note that any code executed by the attacker runs with the privileges of the logged in user. In an attack where code execution fails, the vulnerable application will terminate abnormally while parsing the malicious document.
