Synopsis
========

A vulnerability in Active Record could allow a remote attacker to
inject SQL commands.

Background
==========

Active Record is a Ruby gem that allows database entries to be
manipulated as objects.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-ruby/activerecord      < 2.3.14-r1              >= 2.3.14-r1

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

An Active Record method parameter can mistakenly be used as a scope.

Impact
======

A remote attacker could use specially crafted input to execute
arbitrary SQL statements.

Workaround
==========

The vulnerability may be mitigated by converting the input to an
expected value. This is accomplished by changing instances of
'Post.find_by_id(params[:id])' in code using Active Record to
'Post.find_by_id(params[:id].to_s)'

Resolution
==========

All Active Record users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=dev-ruby/activerecord-2.3.14-r1"
