The (1) SMB and (2) SMB2 dissectors in Wireshark 0.9.0 through 1.2.4 allow remote attackers to cause a denial of service (crash) via a crafted packet that triggers a NULL pointer dereference, as demonstrated by fuzz-2009-12-07-11141.pcap.

Integer overflow in wiretap/erf.c in Wireshark before 1.2.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted erf file, related to an "unsigned integer wrap vulnerability."

Unspecified vulnerability in the AFS dissector in Wireshark 0.9.2 through 1.2.0 allows remote attackers to cause a denial of service (crash) via unknown vectors.

Unspecified vulnerability in the PCNFSD dissector in Wireshark 0.8.20 through 1.0.7 allows remote attackers to cause a denial of service (crash) via crafted PCNFSD packets.

Unspecified vulnerability in Wireshark before 1.0.7 has unknown impact and attack vectors.

Format string vulnerability in the PROFINET/DCP (PN-DCP) dissector in Wireshark 1.0.6 and earlier allows remote attackers to execute arbitrary code via a PN-DCP packet with format string specifiers in the station name. NOTE: some of these details are obtained from third party information.

Wireshark 1.0.4 and earlier allows remote attackers to cause a denial of service via a long SMTP request, which triggers an infinite loop.

The SNMP dissector in Wireshark (formerly Ethereal) 0.99.6 through 0.99.7 allows remote attackers to cause a denial of service (crash) via a malformed packet.

The SCTP dissector in Wireshark (formerly Ethereal) 0.99.5 through 0.99.7 allows remote attackers to cause a denial of service (crash) via a malformed packet.

The TFTP dissector in Wireshark (formerly Ethereal) 0.6.0 through 0.99.7, when running on Ubuntu 7.10, allows remote attackers to cause a denial of service (crash or memory consumption) via a malformed packet, possibly related to a Cairo library bug.
