Description Jan Lieskovsky 2013-05-20 12:58:47 UTC

A denial of service flaw was found in the way Websocket dissector of Wireshark, a network traffic analyzer, processed certain Websocket packet capture files. A remote attacker could provide a specially-crafted Websocket packet capture file that, when processed, would lead to tshark executable crash.
