Details
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.
