An attacker exploits the execution flow of a call to an external library
						to point to an attacker supplied library or code base, allowing the attacker
						to to compromise the application or server via the execution of unauthorized
						code. An application typically makes calls to functions that are a part of
						libraries external to the application. These libraries may be part of the
						operating system or they may be third party libraries. If an attacker can
						redirect an application's attempts to access these libraries to other
						libraries that the attacker supplies, the attacker will be able to force the
						targeted application to execute arbitrary code. This is especially dangerous
						if the targeted application has enhanced privileges. Access can be
						redirected through a number of techniques, including the use of symbolic
						links, search path modification, and relative path manipulation.
