+	    RDoc used to call Kernel#open to open a local file. If a Ruby project
+	    has a file whose name starts with | and ends with tags, the command
+	    following the pipe character is executed. A malicious Ruby project
+	    could exploit it to run an arbitrary command execution against a user
+	    who attempts to run rdoc command.
