Uočene su dvije nepravilnosti u Internet pregledniku Safari koje su posljedica pogrešaka vezanih uz Webkit koji Safari koristi. Jedna od ranjivosti se očituje kao cjelobrojno prepisivanje u Webkit alatu pri obradi podataka o stilu, a druga kao korupcija memorije pri obradu teksta. Obje ranjivosti mogu iskoristiti udaljeni napadači navođenjem korisnika na otvaranje posebno oblikovane web stranice. Ukoliko u tome uspiju, napadač može iskoristiti ranjivosti za izvođenje proizvoljnog programskog koda ili DoS napad. Korisnici se potiču na korištenje nadogradnje.

Note:

Certificate Trust Policy

Several fraudulent SSL certificates were issued by a Comodo affiliate
registration authority. This may allow a man-in-the-middle attacker
to redirect connections and intercept user credentials or other
sensitive information. Safari relies on the certificate store of the
host operating system to determine if an SSL server certificate is
trustworthy. For Mac OS X systems, this issue is addressed with
Security Update 2011-002. For iOS, this issue is addressed with iOS
4.3.2 and iOS 4.2.7. For Windows systems, applying the update
described in Microsoft Knowledge Base Article 2524375 will cause
Safari to regard these certificates as untrusted. The article is
available at http://support.microsoft.com/kb/2524375
