SMB dissector in Ethereal 0.9.3 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via malformed packets that cause Ethereal to dereference a NULL pointer.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
