The ftrace implementation in the Linux kernel before 3.8.8 allows local
users to cause a denial of service (NULL pointer dereference and system
crash) or possibly have unspecified other impact by leveraging the
CAP_SYS_ADMIN capability for write access to the (1) set_ftrace_pid or (2)
set_graph_function file, and then making an lseek system call.
