bazad/iofirewirefamily-null-derefCVE-2017-2388: Null-pointer dereference in IOFireWireFamily.
IOFireWireFamily-null-deref is a proof-of-concept exploit for CVE-2017-2388, a NULL pointer
derefererence in IOFireWireUserClient that was fixed in macOS Sierra 10.12.4. This
vulnerability can be triggered to cause denial of service on devices with a FireWire port.
The function IOFireWireUserClient::setAsyncRef_IsochChannelForceStop did not check that the
parameter inAsyncRef is non-NULL before calling bcopy with inAsyncRef as the source.
The IOFireWireFamily-null-deref code is released into the public domain. As a courtesy I ask that if you reference or use any of this code you attribute it to me.
