  <title>Ruby: Denial of Service vulnerability</title>
  <synopsis>
    The Ruby cgi.rb CGI library is vulnerable to a Denial of Service attack.

  <affected>
    <package name="dev-lang/ruby" auto="yes" arch="*">
      <unaffected range="ge">1.8.5_p2</unaffected>

  <background>
    <p>
    Ruby is a dynamic, open source programming language with a focus on
    simplicity and productivity.
    </p>

  <description>
    <p>
    The read_multipart function of the CGI library shipped with Ruby
    (cgi.rb) does not properly check boundaries in MIME multipart content.
    This is a different issue than GLSA 200611-12.
    </p>
  </description>
  <impact type="normal">
    <p>
    The vulnerability can be exploited by sending the cgi.rb library a
    crafted HTTP request with multipart MIME encoding that contains a
    malformed MIME boundary specifier. Successful exploitation of the
    vulnerability causes the library to go into an infinite loop.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All Ruby users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/ruby-1.8.5_p2&quot;</code>
  </resolution>
