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 a memory corruption vulnerability in Mozilla Foundation's family of browser products. The flaw exists in the XBL (Extensible Binding Language) component and specifically happens via dynamic manipulation of XUL tags inside event handlers. A remote attacker can exploit this vulnerability to execute arbitrary code in the security context of the target browser. In case of an attack where code injection is not successful, Firefox may terminate abnormally. In case of an attack where code injection and execution is successful, the behavior of the target will depend on the intended purpose of the injected code. Any injected code will be executed within the security context of the currently logged in user.
