Synopsis
========

A vulnerability has been discovered in RDoc, which can lead to execution
of arbitrary code.

Background
==========

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

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

Package        Vulnerable    Unaffected
-------------  ------------  ------------
dev-ruby/rdoc  < 6.6.3.1     >= 6.6.3.1

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

A vulnerability has been discovered in RDoc. Please review the CVE
identifier referenced below for details.

Impact
======

When parsing .rdoc_options (used for configuration in RDoc) as a YAML
file, object injection and resultant remote code execution are possible
because there are no restrictions on the classes that can be restored.

When loading the documentation cache, object injection and resultant
remote code execution are also possible if there were a crafted cache.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All RDoc users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-ruby/rdoc-6.6.3.1"
