Synopsis

A vulnerability has been found in RDoc which allows for command
injection.

Background
==========

RDoc produces HTML and command-line documentation for Ruby projects.

Affected packages
=================

Package        Vulnerable    Unaffected

Description
===========

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 the rdoc command.

Workaround

Resolution

All RDoc users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-ruby/rdoc-6.3.2"
