    Synopsis
    ========

    A vulnerability in XMLRPC.iPIMethods allows remote attackers to execute
    arbitrary commands.

    Background
    ==========

    Ruby is an interpreted scripting language for quick and easy
    object-oriented programming. XML-RPC is a remote procedure call
    protocol encoded in XML.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 dev-lang/ruby < 1.8.2-r2 >= 1.8.2-r2

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

    Nobuhiro IMAI reported that an invalid default value in "utils.rb"
    causes the security protections of the XML-RPC server to fail.

    Impact
    ======

    A remote attacker could exploit this vulnerability to execute arbitrary
    commands.

    Workaround
    ==========

    There is no known workaround at this time.

    Resolution
    ==========

    All Ruby users should upgrade to the latest available version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.8.2-r2"
