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.

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.
