Vulnerability Note VU#243153

Mozilla may associate persisted XUL attributes with an incorrect URL

Original Release date: 02 Jun 2006 | Last revised: 09 Feb 2007


Mozilla can allow persisted XUL attributes to associate with the wrong URL. This may allow a remote attacker to execute arbitrary code.



XUL is an XML-based user interface language, which is used by Mozilla.

Persisted XUL

XUL elements with the persist attribute maintain their values after the window is closed. These values are stored in the localstore.rdf file.

The problem

Some persisted XUL attributes can be associated with the wrong URL. Mozilla Firefox and Thunderbird are reported to be vulnerable.


By convincing a user to view a specially crafted HTML document (e.g., a web page, an HTML email message, or an HTML email attachment), an attacker may be able to execute arbitrary code with the privileges of the user.
