Kod programskog paketa Iceweasel uočen je veći broj sigurnosnih nepravilnosti. Nedostaci uključuju CSRF ranjivost, nepravilan rad "ParanoidFragmentSink" komponente, nepravilnu obradu rekurzivnih "eval()" poziva, pogreške u radu mehanizma za prikaz sadržaja, neodgovarajuće rukovanje memorijom, itd. Zlonamjerni napadač može iskorititi sve opisane ranjivosti kako bi izveo DoS (eng. Denial of Service) napad ili pokrenuo proizvoljan programski kod na sustavu. Savjetuje se instalacija programske nadogradnje.
