brokentooth POC for CVE-2018-4327 at least I think so since CVE-2018-4327 and CVE-2018-4330 were both discussed by @SparkZheng but it's not clear from him which one relates to which bug but since he described this one first I'm taking a guess. Tested on iPhone 6S 11.3.1 Should work until 11.4 Let...

Probado en iPhone 6S 11.3.1 Debería funcionar hasta 11....

macOS < 10.14.3 / iOS < 12.1.3 - Arbitrary mach Port Name Deallocation in XPC Services due to Invalid mach Message Parsing in _xpc_serializer_unpack
/ xpcserializerunpack in libxpc parses mach messages which contain xpc messages. There are two reasons for an xpc mach message to contain descriptors: if the message body is large, then it's sent as a MACHMSGOOLDESCRIPTOR. Also if the message contains other port resources eg memory entry ports th...
