Overview
A vulnerability in the way Mozilla products and derivative programs handle certain XBL methods could allow a remote attacker to execute arbitrary code on a vulnerable system.
Description
The Mozilla browser and derived products include support for the Extensible Bindings Language (XBL), a markup language that defines special new elements, or "bindings" for Mozilla's XML-based User interface Language (XUL) widgets and HTML elements. A vulnerability has been discovered in the way that Mozilla and derived products handle some methods of XBL bindings. Mozilla Foundation Security Advisory 2006-14 states the following: Using the eval associated with methods of an XBL binding it was possible to create JavaScript functions that would get compiled with the wrong privileges, allowing the attacker to run code of their choice with the full permission of the user running the browser. This could be used to install spyware or viruses. Note: Thunderbird shares the JavaScript engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. |
Impact
A remote attacker may be able to run code of their choosing on an affected system. The attacker-supplied code would be executed with the permissions of the user running the vulnerable program. |
