The host is installed with Wireshark 1.6.x before 1.6.12 or 1.8.x before 1.8.4 and is prone to denial of service vulnerability. A flaw is present in the application, which fails to handle the dissect_isakmp function in epan/dissectors/packet-isakmp.c in the ISAKMP dissector. Successful exploitation allows remote attackers to cause a denial of service (application crash).
