iMessage - Decoding NSSharedKeyDictionary can read ObjC Object at Attacker Controlled Address

During processing of incoming iMessages, attacker controlled data is deserialized using the NSUnarchiver API. One of the classes that is allowed to be decoded from the incoming data is NSDictionary. However, due to the logic of NSUnarchiver, all subclasses of NSDictionary that also implement secu...

iMessage - Decoding NSSharedKeyDictionary Can Read Object Out of Bounds Exploit

When an NSKeyedUnarchiver decodes an object, it first allocates the object using allocWithZone, and then puts the object into a dictionary for temporary objects. It then calls the appropriate initWithCoder: on the allocated object. If initWithCoder: or any method it calls decodes the same object,...
