[bgpd] low-impact DoS: crash on malformed community with debug set
2007-09-07 Paul Jakma <paul.jakma@sun.com> * (general) bgpd can be made crash by remote peers if debug bgp updates is set, due to NULL pointer dereference. Reported by "Mu Security Research Team", <security@musecurity.com>. * bgp_attr.c: (bgp_attr_community) If community length is 0, don't set the community-present attribute bit, just return early. * bgp_debug.c: (community_str,community_com2str) Check com pointer before dereferencing.
