Title: XBL scripts ran even when Javascript disabled
Severity: Low
Reporter: moz_bug_r_a4
Products: Firefox, Thunderbird, Mozilla Suite

Fixed in: Firefox 1.0.5
  Thunderbird 1.0.5
  Mozilla Suite 1.7.10


Scripts in XBL controls from web content continued to be run even when Javascript was disabled. By itself this causes no harm, but it could be combined with most script-based exploits to attack people running vulnerable versions who thought disabling javascript would protect them.

In the Thunderbird and Mozilla Suite mail clients Javascript is disabled by default for protection against denial-of-service attacks and worms; this vulnerability could be used to bypass that protection.


Upgrade to a fixed version
