An attacker gains control of a process that is assigned elevated
						privileges in order to execute arbitrary code with those privileges. Some
						processes are assigned elevated privileges on an operating system, usually
						through association with a particular user, group, or role. If an attacker
						can hijack this process, they will be able to assume its level of prevelege
						in order to execute their own code. Processes can be hijacked through
						inproper handling of user input (for example, a buffer overflow or certain
						types of injection attacks) or by utilizing system utilities that support
						process control that have been inadequately secured.
