Mozilla XBL binding vulnerability
Mozilla products fail to properly restrict access to privileged XBL bindings. This vulnerability may allow a remote, unauthenticated attacker to execute arbitrary code.
According to Mozilla, XBL "is a markup language that defines special new elements, or 'bindings' for XUL widgets (and for HTML elements ...) ".
Privileged XBL bindings may be accessible by user controlled content in a way that could allow a remote attacker to execute arbitrary code. Specifically, the valueOf.call()and valueOf.apply() routines can be leveraged by an attacker to compile and execute arbitrary code with the privileges of the attacked XBL binding.
For a list of affected products refer to Mozilla Foundation Security Advisory 2006-16.
A remote, unauthenticated attacker may be able to execute arbitrary code on a vulnerable system.
