The AH parser in tcpdump before 4.9.0 has a buffer overflow in print-ah.c:ah_print().

The force printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.

The osi_print_cksum function in print-isoclns.c in the ethernet printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read and crash) via a crafted (1) length, (2) offset, or (3) base pointer checksum value.

The rpki_rtr_pdu_print function in print-rpki-rtr.c in the TCP printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read or write and crash) via a crafted header length in an RPKI-RTR Protocol Data Unit (PDU).

Integer signedness error in the mobility_opt_print function in the IPv6 mobility printer in tcpdump before 4.7.2 allows remote attackers to cause a denial of service (out-of-bounds read and crash) or possibly execute arbitrary code via a negative length value.

Buffer overflow in the ppp_hdlc function in print-ppp.c in tcpdump 4.6.2 and earlier allows remote attackers to cause a denial of service (crash) cia a crafted PPP packet.

tcpdump 3.8 through 4.6.2 might allow remote attackers to obtain sensitive information from memory or cause a denial of service (packet loss or segmentation fault) via a crafted Ad hoc On-Demand Distance Vector (AODV) packet, which triggers an out-of-bounds memory access.

Multiple Integer underflows in the geonet_print function in tcpdump 4.5.0 through 4.6.2, when in verbose mode, allow remote attackers to cause a denial of service (segmentation fault and crash) via a crafted length value in a Geonet frame.

Integer underflow in the olsr_print function in tcpdump 3.9.6 through 4.6.2, when in verbose mode, allows remote attackers to cause a denial of service (crash) via a crafted length value in an OLSR frame.

Integer overflow in print-bgp.c in the BGP dissector in tcpdump 3.9.6 and earlier allows remote attackers to execute arbitrary code via crafted TLVs in a BGP packet, related to an unchecked return value.

Off-by-one buffer overflow in the parse_elements function in the 802.11 printer code (print-802_11.c) for tcpdump 3.9.5 and earlier allows remote attackers to cause a denial of service (crash) via a crafted 802.11 frame. NOTE: this was originally referred to as heap-based, but it might be stack-based.

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.
