  * SECURITY UPDATE: A bgpd could be crashed if a peer sent a malformed
    OPEN message or a malformed COMMUNITY attribute. Only configured peers can
    do this.
  * debian/patches/92_ubuntu_fix_dos_malformed_community.dpatch: patch to fix
    the DoS. Latest unstable debian package is 0.99.9 which fixes this
    upstream
