Vulnerability Note VU#243153
Mozilla may associate persisted XUL attributes with an incorrect URL
OverviewMozilla can allow persisted XUL attributes to associate with the wrong URL. This may allow a remote attacker to execute arbitrary code.
I. DescriptionXUL
XUL is an XML-based user interface language, which is used by Mozilla.
Persisted XUL

The problem

II. ImpactBy 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.
III. SolutionApply an update
Refer to Mozilla Foundation Security Advisory 2006-35 for fixed versions of Mozilla products.
