Synopsis
========

Multiple vulnerabilities were found in Ruby on Rails, the worst of
which allowing for execution of arbitrary code.

Background
==========

Ruby on Rails is a web-application and persistence framework.

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

——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 dev-ruby/rails < 2.3.18 >= 2.3.18 *
——————————————————————-
NOTE: Packages marked with asterisks require manual intervention!

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

Multiple vulnerabilities have been discovered in Ruby on Rails. Please
review the CVE identifiers referenced below for details.

Impact
======

A remote attacker could execute arbitrary code or cause a Denial of
Service condition. Furthermore, a remote attacker may be able to
execute arbitrary SQL commands, change parameter names for form inputs
and make changes to arbitrary records in the system, bypass intended
access restrictions, render arbitrary views, inject arbitrary web
script or HTML, or conduct cross-site request forgery (CSRF) attacks.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ruby on Rails 2.x users should upgrade to the latest version:

# emerge –sync
# emerge –ask –oneshot –verbose “>=dev-ruby/rails-2.3.18”

NOTE: All applications using Ruby on Rails should also be configured to
use the latest version available by running “rake rails:update” inside
the application directory.

NOTE: This is a legacy GLSA and stable updates for Ruby on Rails,
including the unaffected version listed above, are no longer available
from Gentoo. It may be possible to upgrade to the 3.2, 4.0, or 4.1
branches, however these packages are not currently stable.
