iMessage - NSArray Deserialization can Invoke Subclass that does not Retain References

When deserializing a class with initWithCoder, subclasses of that class can also be deserialized so long as they do not override initWithCoder and implement all methods that require a concrete implementation. PFArray is such a subclass of NSArray. When a PFArray is deserialized, it is deserialize...

iMessage - NSKeyedUnarchiver Deserialization Allows file Backed NSData Objects The class NSDataFileBackedFuture can be deserialized even if secure encoding is enabled. This class is a file-backed NSData object that loads a local file into memory when the NSData bytes selector is called. This...

macOS / iOS NSKeyedUnarchiver - Use-After-Free of ObjC Objects when Unarchiving OITSUIntDictionary I

macOS / iOS NSKeyedUnarchiver - Use-After-Free of ObjC Objects when Unarchiving OITSUIntDictionary Instances When deserializing NSObjects with the NSArchiver API 1, one can supply a whitelist of classes that are allowed to be unarchived. In that case, any object in the archive whose class is not...

iMessage - Memory Corruption when Decoding NSKnownKeysDictionary1 Exploit

There is a memory corruption vulnerability when decoding an object of class NSKnownKeysDictionary1. This class decodes an object of type NSKnownKeysMappingStrategy1, which decodes a length member which is supposed to represent the length of the keys of the dictionary. However, this member is...

macOS / iOS NSKeyedUnarchiver - Use-After-Free of ObjC Objects when Unarchiving OITSUIntDictionary Instances

When deserializing NSObjects with the NSArchiver API 1, one can supply a whitelist of classes that are allowed to be unarchived. In that case, any object in the archive whose class is not whitelisted will not be deserialized. Doing so will also cause the NSKeyedUnarchiver to "requireSecureCoding"...
