Synopsis
========

Multiple vulnerabilities have been found in Ruby, allowing
context-dependent attackers to cause a Denial of Service condition.

Background
==========

Ruby is an object-oriented scripting language.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-lang/ruby              < 2.0.0_p598           *>= 1.9.3_p551
                                                        >= 2.0.0_p598

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

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

Impact
======

A context-dependent attacker could possibly execute arbitrary code with
the privileges of the process, cause a Denial of Service condition, or
bypass security restrictions.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Ruby 1.9 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.9.3_p551"
