  <background>
    <p>nginx is a robust, small, and high performance HTTP and reverse proxy
      server.
    </p>
  </background>
  <description>
    <p>An error in ngx_http_mp4_module.c could cause a buffer overflow.</p>
    
    <p>NOTE: nginx must have been emerged with USE="nginx_modules_http_mp4" in
      order to be affected by this vulnerability.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could entice a user to place a specially crafted MP4
      file on the nginx server, possibly resulting in execution of arbitrary
      code with the privileges of the process or a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All nginx users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=www-servers/nginx-1.0.15"
    </code>
