    <p>
    The following vulnerabilities were discovered:
    </p>
    <ul>
    <li>sameer
    reported that lib/action_controller/cgi_process.rb removes the
    :cookie_only attribute from the default session options
    (CVE-2007-6077), due to an incomplete fix for CVE-2007-5380 (GLSA
    200711-17).</li>
    <li>Tobias Schlottke reported that the :limit and
    :offset parameters of ActiveRecord::Base.find() are not properly
    sanitized before being processed (CVE-2008-4094).</li>
    <li>Steve from
    Coderrr reported that the CRSF protection in protect_from_forgery()
    does not parse the text/plain MIME format (CVE-2008-7248).</li>
    <li>Nate reported a documentation error that leads to the assumption
    that a block returning nil passed to
    authenticate_or_request_with_http_digest() would deny access to the
    requested resource (CVE-2009-2422).</li>
    <li>Brian Mastenbrook reported
    an input sanitation flaw, related to multibyte characters
    (CVE-2009-3009).</li>
    <li>Gabe da Silveira reported an input sanitation
    flaw in the strip_tags() function (CVE-2009-4214).</li>
    <li>Coda Hale
    reported an information disclosure vulnerability related to HMAC
    digests (CVE-2009-3086).</li>
    </ul>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could send specially crafted requests to a vulnerable
    application, possibly leading to the execution of arbitrary SQL
    statements or a circumvention of access control. A remote attacker
    could also conduct session fixation attacks to hijack a user's session
    or bypass the CSRF protection mechanism, or furthermore conduct
    Cross-Site Scripting attacks or forge a digest via multiple attempts.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Ruby on Rails 2.3.x users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-ruby/rails-2.3.5&quot;</code>
    <p>
    All Ruby on Rails 2.2.x users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;=dev-ruby/rails-2.2.3-r1&quot;</code>
    <p>
    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.
    </p>
