Mozilla Foundation Security Advisory 2006-54

Title: XSS with XPCNativeWrapper(window).Function(...)
Impact: High
Announced: July 25, 2006
Reporter: shutdown
Products: Firefox, Thunderbird, SeaMonkey

Fixed in: Firefox 1.5.0.5
  Thunderbird 1.5.0.5
  SeaMonkey 1.0.3

Description

shutdown reports that cross-site scripting (XSS) attacks could be performed using the construct XPCNativeWrapper(window).Function(...), which created a function that appeared to belong to the window in question even after it had been navigated to the target site.

This vulnerability was introduced during Firefox 1.5 development, it does not affect Firefox 1.0 or Mozilla Suite 1.7

Thunderbird shares the browser engine with Firefox and would be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from enabling JavaScript in mail.

Workaround

Disable JavaScript until you can upgrade to a fixed version. Do not enable JavaScript in mail clients such as Thunderbird.
