Who is Vulnerable?
Vulnerability Description Mozilla Firefox is a web browser developed by Mozilla Foundation. The browser is capable of interpreting and rendering many types of content published on the Internet, including various versions of HTML, XML, XUL, JavaScript, various graphics formats, and so on. The browser runs on the Windows, Macintosh, Unix and Linux based platforms. A code execution vulnerability exists in Mozilla Firefox. The vulnerability is due to an error while handling plugins parameters contained in a malicious object tag. A remote attacker can exploit this vulnerability by enticing a target user to visit a specially crafted web page. Exploitation of the vulnerability can result in arbitrary code execution in the context of the application. In attack scenarios where code execution is successful the behavior of the target system depends entirely on the logic of the injected code, which would run within the security context of the currently logged in user. In situations where code execution is not successful the affected application may terminate abnormally.
