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, Cascading Style Sheets, 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 the Mozilla Firefox web browser. The vulnerable application incorrectly parses a series of crafted HTML tags, resulting in memory corruption. A malicious attacker can exploit this vulnerability by enticing a user to open a specially crafted web page, which may result in the injection and execution of arbitrary code on the target host. In case of an attack where code injection is not successful, the target application may terminate or lock up. The Firefox process will remain resident in memory after manual shutdown of the application. All pages open in the targeted application will be inaccessible. In case of an attack where code injection and execution is uccessful, the behavior of the target host is dependent on the intented purpose of the injected code. Any code execution will be within the privileges of the currently logged in user.
