A denial of service flaw was found in the way ICMPv6 dissector of Wireshark, a network traffic analyzer, performed dissection of certain ICMPv6 packet capture files. A remote attacker could provide a specially-crafted ICMPv6 packet capture that, once processed, would lead to excessive CPU consumption or into situation where tshark executable would enter an infinite loop, when trying to process the crafted packet.
