U radu popularnog web preglednika Safari, uočene su višestruke sigurnosne ranjivosti. Točnije nedostaci su nastali u paketima ImageIO, libxml i WebKit. Propusti se odnose na nepravilno upravljanje memorijom, prepisivanje spremnika gomile prilikom obrade TIFF slikovnih datoteka, nepravilnu obradu "window.console._inspectorCommandLineAPI" značajki, itd. Uspješna zloupotreba može rezultirati izvođenjem proizvoljnog programskog koda, pokretanjem MITM (eng. man-in-the-middle), XSS (eng. cross-site scripting) i DoS napada, te otkrivanjem osjetljivih informacija. Korisnicima se savjetuje instalacija dostupne programske nedogradnje.
