epan/dissectors/packet-ncp2222.inc in the NCP dissector in Wireshark 2.0.x before 2.0.3 does not properly initialize memory for search patterns, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - epan/dissectors/packet-ncp2222.inc in the NCP dissector in Wireshark 2.0.x before 2.0.3 does not properly     initialize memory for search patterns, which allows remote attackers to cause a denial of service     (application crash) via a crafted packet. (CVE-2016-4076)

Note that Nessus relies on the presence of the package as reported by the vendor.

  - GSM CBCH dissector
  - IAX2 dissector
  - IEEE 802.11 dissector
  - MS-WSP dissector
  - NCP dissector
  - PKTC dissector
  - TShark

The version of Wireshark installed on the remote Mac OS X host is 2.0.x prior to 2.0.3. It is, therefore, affected by multiple denial of service vulnerabilities in the following components :

  - GSM CBCH dissector
