The software, when opening a file or directory, does not
					sufficiently account for when the name is associated with a hard link to a
					target that is outside of the intended control sphere. This could allow an
					attacker to cause the software to operate on unauthorized
					files.Failure for a system to check for hard links can result in vulnerability
						to different types of attacks. For example, an attacker can escalate their
						privileges if a file used by a privileged program is replaced with a hard
						link to a sensitive file (e.g. /etc/passwd). When the process opens the
						file, the attacker can assume the privileges of that process.
