U radu Iceweasel paketa, web preglednika temeljenog na Firefox-u, uočene su višestruke sigurnosne nepravilnosti. Propusti se odnose na rad funkcije "ParanoidFragmentSink" i "eval()", pojavu prepisivanja spremnika, nepravilno rukovanje memorijom u JSON implementaciji, CSRF (eng. Cross-site request forgery) ranjivost te neodgovarajuću implementaciju dodataka za preglednik. Propusti se mogu iskoristiti za pokretanje proizvoljnog programskog koda te izvođenje DoS napada putem posebno oblikovanog dokumenta. Korisnicima se savjetuje korištenje ispravljenih i dostupnih inačica paketa.
