The bgp_update_print function in tcpdump 3.x does not properly handle a -1 return value from the decode_prefix4 function, which allows remote attackers to cause a denial of service (infinite loop) via a crafted BGP packet.

The isis_print function, as called by isoclns_print, in tcpdump 3.9.1 and earlier allows remote attackers to cause a denial of service (infinite loop) via a zero length, as demonstrated using a GRE packet.

tcpdump 3.8.3 and earlier allows remote attackers to cause a denial of service (infinite loop) via a crafted (1) BGP packet, which is not properly handled by RT_ROUTING_INFO, or (2) LDP packet, which is not properly handled by the ldp_print function.

The rsvp_print function in tcpdump 3.9.1 and earlier allows remote attackers to cause a denial of service (infinite loop) via a crafted RSVP packet of length 4.

The L2TP protocol parser in tcpdump 3.8.1 and earlier allows remote attackers to cause a denial of service (infinite loop and memory consumption) via a packet with invalid data to UDP port 1701, which causes l2tp_avp_print to use a bad length value w...

The print_attr_string function in print-radius.c for tcpdump 3.8.1 and earlier allows remote attackers to cause a denial of service (segmentation fault) via a RADIUS attribute with a large length value.

The rawprint function in the ISAKMP decoding routines (print-isakmp.c) for tcpdump 3.8.1 and earlier allows remote attackers to cause a denial of service (segmentation fault) via malformed ISAKMP packets that cause invalid "len" or "loc" values to be...

Unknown vulnerability in tcpdump before 3.7.2 related to an inability to "Handle unknown RADIUS attributes properly," allows remote attackers to cause a denial of service (infinite loop), a different vulnerability than CAN-2003-0093.

isakmp_sub_print in tcpdump 3.6 through 3.7.1 allows remote attackers to cause a denial of service (CPU consumption) via a certain malformed ISAKMP packet to UDP port 500, which causes tcpdump to enter an infinite loop.

The RADIUS decoder in tcpdump 3.6.2 and earlier allows remote attackers to cause a denial of service (crash) via an invalid RADIUS packet with a header length field of 0, which causes tcpdump to generate data within an infinite loop.
