Multiple security vulnerabilities have been found in the Firefox web browser, Mozilla SeaMonkey, and Thunderbird email client. All other products based on Mozilla components, and especially Gecko, are likely affected. If you use any of those products you should either disable JavaScript or immediately upgrade to Mozilla Firefox 1.5.0.4, Mozilla Thunderbird 1.5.0.4, or SeaMonkey 1.0.2.
