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
------------- ------------ ------------
dev-ruby/rdoc < 6.3.2 >= 6.3.2

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

Impact
=====
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 the rdoc command.

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 ">Þv-ruby/rdoc-6.3.2"
