VMScore: 755

Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P

libnetcore in Apple iOS prior to 8.1.3, Apple OS X prior to 10.10.2, and Apple TV prior to 7.0.3 does not verify that certain values have the expected data type, which allows malicious users 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.
