CVE-2014-4492

Status Candidate

Overview

libnetcore in Apple iOS before 8.1.3, Apple OS X before 10.10.2, and Apple TV before 7.0.3 does not verify that certain values have the expected data type, which allows attackers to execute arbitrary code in an _networkd context via a crafted XPC message from a sandboxed app, as demonstrated by lack of verification of the XPC dictionary data type.

Mac OS X Networkd XPC Type Confusion Sandbox Escape
Posted Nov 17, 2015
Authored by Google Security Research, Ian Beer

networkd is the system daemon which implements the com.apple.networkd XPC service. It's unsandboxed but runs as its own user. com.apple.networkd is reachable from many sandboxes including the Safari WebProcess and ntpd (plus all those which allow system-network). networkd parses quite complicated XPC messages and there are many cases where xpc_dictionary_get_value and xpc_array_get_value are used without subsequent checking of the type of the returned value.
