Wireshark 1.4.x before 1.4.13 and 1.6.x before 1.6.8 allows remote attackers to cause a denial of service (infinite loop) via vectors related to the (1) ANSI MAP, (2) ASF, (3) IEEE 802.11, (4) IEEE 802.3, and (5) LTP dissectors.

The mp2t_process_fragmented_payload function in epan/dissectors/packet-mp2t.c in the MP2T dissector in Wireshark 1.4.x before 1.4.12 and 1.6.x before 1.6.6 allows remote attackers to cause a denial of service (application crash) via a packet containing an invalid pointer value that triggers an incorrect memory-allocation attempt.

The pcap_process_pseudo_header function in wiretap/pcap-common.c in Wireshark 1.4.x before 1.4.12 and 1.6.x before 1.6.6 allows remote attackers to cause a denial of service (application crash) via a WTAP_ENCAP_ERF file containing an Extension or Multi-Channel header with an invalid pseudoheader size, related to the pcap and pcap-ng file parsers.

epan/dissectors/packet-ansi_a.c in the ANSI A dissector in Wireshark 1.4.x before 1.4.12 and 1.6.x before 1.6.6 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a malformed packet.

The lanalyzer_read function in wiretap/lanalyzer.c in Wireshark 1.4.x before 1.4.11 and 1.6.x before 1.6.5 allows remote attackers to cause a denial of service (application crash) via a Novell capture file containing a record that is too small.

wiretap/iptrace.c in Wireshark 1.4.x before 1.4.11 and 1.6.x before 1.6.5 allows remote attackers to cause a denial of service (application crash) via a long packet in an AIX iptrace file.

Wireshark 1.4.x before 1.4.11 and 1.6.x before 1.6.5 allows remote attackers to cause a denial of service (application crash) via a long packet in a (1) Accellent 5Views (aka .5vw) file, (2) I4B trace file, or (3) NETMON 2 capture file.

Buffer overflow in the reassemble_message function in epan/dissectors/packet-rlc.c in the RLC dissector in Wireshark 1.4.x before 1.4.11 and 1.6.x before 1.6.5 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a series of fragmented RLC packets.

Wireshark 1.4.x before 1.4.11 and 1.6.x before 1.6.5 does not properly perform certain string conversions, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted packet, related to epan/to_str.c.

The dissect_packet function in epan/packet.c in Wireshark 1.4.x before 1.4.11 and 1.6.x before 1.6.5 allows remote attackers to cause a denial of service (application crash) via a long packet in a capture file, as demonstrated by an airopeek file.

Heap-based buffer overflow in the erf_read_header function in wiretap/erf.c in the ERF file parser in Wireshark 1.4.0 through 1.4.9 and 1.6.x before 1.6.3 allows remote attackers to cause a denial of service (application crash) via a malformed file.

The dissect_infiniband_common function in epan/dissectors/packet-infiniband.c in the Infiniband dissector in Wireshark 1.4.0 through 1.4.9 and 1.6.x before 1.6.3 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a malformed packet.
