          <p>It was discovered that Quagga, an IP routing daemon, could
          no longer process the Internet routing table due to broken
          handling of multiple 4-byte AS numbers in an AS path.  If such
          a prefix is received, the BGP daemon crashes with an assert
          failure, leading to a denial of service.</p>
