Synopsis
========

Ruby on Rails has some weaknesses potentially allowing a Denial of
Service and maybe the remote execution of arbitrary Ruby scripts.

Background
==========

Ruby on Rails is an open-source web framework.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-ruby/rails < 1.1.6 >= 1.1.6

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

The Ruby on Rails developers have corrected some weaknesses in
action_controller/, relative to the handling of the user input and the
LOAD_PATH variable. A remote attacker could inject arbitrary entries
into the LOAD_PATH variable and alter the main Ruby on Rails process.
The security hole has only been partly solved in version 1.1.5. Version
1.1.6 now fully corrects it.

Impact
======

A remote attacker that would exploit these weaknesses might cause a
Denial of Service of the web framework and maybe inject arbitrary Ruby
scripts.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ruby on Rails users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-ruby/rails-1.1.6"
