Description Jan Lieskovsky 2013-05-20 12:57:11 UTC

A denial of service flaw was found in the way ETCH dissector of Wireshark, a network traffic analyzer, processed certain ETCH packet capture files. A remote attacker could provide a specially-crafted ETCH packet capture file that, when processed, would lead to wireshark executable to enter large loop (denial of service) when trying to dissect that file.
