epan/dissectors/packet-nfs.c in the NFS dissector in Wireshark 1.4.x before 1.4.14, 1.6.x before 1.6.9, and 1.8.x before 1.8.1 allows remote attackers to cause a denial of service (loop and CPU consumption) via a crafted packet.

Security readout for executives and security teams

A flaw in Wireshark's NFS packet parser can make vulnerable Wireshark versions hang and consume CPU when they process a specially crafted packet. The business impact is analyst workstation or packet-analysis service disruption, not data theft or code execution based on the supplied sources. Exposure is most likely where old Wireshark builds process live traffic or capture files containing NFS packets. Internet-facing services are not directly implicated by the sources; the vulnerable component is Wireshark packet dissection. Treat this as a targeted operational reliability issue. Prioritize teams that use Wireshark for incident response, network monitoring, or capture-file review, especially if they handle untrusted traffic captures. Mitigation focus: Upgrade Wireshark 1.4.x to 1.4.14 or later.; Upgrade Wireshark 1.6.x to 1.6.9 or later.; Upgrade Wireshark 1.8.x to 1.8.1 or later..
