An invalid read flaw was found in the way DTN dissector of Wireshark, a network traffic analyzer, performed dissection of certain DTN packet capture files. A remote attacker could provide a specially-crafted DTN packet / packet capture that, when processed, would lead tshark executable crash, when trying to process the crafted packet / packet capture file.
