  <description>
    <p>A buffer overflow can be triggered in the URL parsing functions of the
      PECL HTTP extension. This allows overflowing
      a buffer with data originating from an arbitrary HTTP request.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker, through a specially crafted URI, could possibly
      execute arbitrary code with the privileges of the process.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All PECL HTTP users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=dev-php/pecl-http-2.5.6"
    </code>
