A security flaw was found in the Wireshark's SMTP dissector -- routines for SMTP packet disassembly. A remote attacker could use this flaw to cause a denial of service (infinite loop) via sending a large SMTP request to port 25.

Use-after-free vulnerability in the dissectq931causeie function in packet-q931.c in the Q.931 dissector in Wireshark 0.10.3 through 1.0.3 allows remote attackers to cause a denial of service (application crash or abort) via certain packets that trigger an exception.
packet-usb.c in the USB dissector in Wireshark 0.99.7 through 1.0.3 allows remote attackers to cause a denial of service (application crash or abort) via a malformed USB Request Block (URB).
The dissectbtacl function in packet-bthciacl.c in the Bluetooth ACL dissector in Wireshark 0.99.2 through 1.0.3 allows remote attackers to cause a denial of service (application crash or abort) via a packet with an invalid length, related to an erroneous tvbmemcpy call.
wtap.c in Wireshark 0.99.7 through 1.0.3 allows remote attackers to cause a denial of service (application abort) via a malformed Tamos CommView capture file (aka .ncf file) with an "unknown/unexpected packet type" that triggers a failed assertion.
packet-frame in Wireshark 0.99.2 through 1.0.3 does not properly handle exceptions thrown by post dissectors, which allows remote attackers to cause a denial of service (application crash) via a certain series of packets, as demonstrated by enabling the (1) PRP or (2) MATE post dissector.
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."
The DCERPC/NT dissector in Wireshark 0.10.10 through 1.0.9 and 1.2.0 through 1.2.2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a file that records a malformed packet trace. NOTE: some of these details are obtained from third party information.
Unspecified vulnerability in the OpcUa (OPC UA) dissector in Wireshark 0.99.6 through 1.0.8 and 1.2.0 through 1.2.1 allows remote attackers to cause a denial of service (memory and CPU consumption) via malformed OPCUA Service CallRequest packets.
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.
Multiple unspecified vulnerabilities in Wireshark 1.2.0 allow remote attackers to cause a denial of service (application crash) via a file that records a malformed packet trace and is processed by the (1) Bluetooth L2CAP, (2) RADIUS, or (3) MIOP dissector. NOTE: it was later reported that the RADIUS issue also affects 0.10.13 through 1.0.9.
The Check Point High-Availability Protocol (CPHAP) dissector in Wireshark 0.9.6 through 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted FWHAMYSTATE packet.
Unspecified vulnerability in Wireshark 0.99.6 through 1.0.6 allows remote attackers to cause a denial of service (crash) via a crafted Tektronix .rf5 file.
Unspecified vulnerability in Wireshark before 1.0.7 has unknown impact and attack vectors.
Unspecified vulnerability in the LDAP dissector in Wireshark 0.99.2 through 1.0.6, when running on Windows, allows remote attackers to cause a denial of service (crash) via unknown attack vectors.
Buffer overflow in the SigComp Universal Decompressor Virtual Machine dissector in Wireshark 0.10.8 through 1.0.13 and 1.2.0 through 1.2.8 has unknown impact and remote attack vectors.
The SMB dissector in Wireshark 0.99.6 through 1.0.13, and 1.2.0 through 1.2.8 allows remote attackers to cause a denial of service (NULL pointer dereference) via unknown vectors.
Buffer overflow in the ASN.1 BER dissector in Wireshark 0.10.13 through 1.0.13 and 1.2.0 through 1.2.8 has unknown impact and remote attack vectors.
The SigComp Universal Decompressor Virtual Machine dissector in Wireshark 0.10.7 through 1.0.13 and 1.2.0 through 1.2.8 allows remote attackers to cause a denial of service (infinite loop) via unknown vectors.
The SMB PIPE dissector in Wireshark 0.8.20 through 1.0.13 and 1.2.0 through 1.2.8 allows remote attackers to cause a denial of service (NULL pointer dereference) via unknown vectors.
epan/dissectors/packet-ldap.c in Wireshark 1.0.x, 1.2.0 through 1.2.14, and 1.4.0 through 1.4.3 allows remote attackers to cause a denial of service (memory consumption) via (1) a long LDAP filter string or (2) an LDAP filter string containing many elements.
Multiple stack consumption vulnerabilities in the dissectmscompressedstring and dissectmscldapstring functions in Wireshark 1.0.x, 1.2.0 through 1.2.14, and 1.4.0 through 1.4.3 allow remote attackers to cause a denial of service (infinite recursion) via a crafted (1) SMB or (2) Connection-less LDAP (CLDAP) packet.
epan/dissectors/packet-ntlmssp.c in the NTLMSSP dissector in Wireshark before 1.4.4 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted .pcap file.
