epan/dissectors/packet-ieee80211.c in the IEEE 802.11 dissector in Wireshark 2.x before 2.0.2 mishandles the Grouping subfield, which allows remote attackers to cause a denial of service (buffer over-read and application crash) via a crafted packet.

Security readout for executives and security teams

Plain-English summary

A flaw in Wireshark’s Wi‑Fi packet parser can crash the application when it processes a specially crafted 802.11 packet. This is mainly a denial-of-service issue for analysts and systems using vulnerable Wireshark versions, not evidence of server compromise or code execution.

Executive priority

Handle through normal vulnerability management unless vulnerable Wireshark is heavily used for wireless analysis. The business impact is analyst tool disruption, not confirmed data theft or remote system takeover.

Technical view

CVE-2016-4416 affects the IEEE 802.11 dissector in Wireshark 2.x before 2.0.2. The dissector mishandles the Grouping subfield, causing a buffer over-read and application crash when parsing a crafted packet.

Likely exposure

Exposure is most likely where Wireshark 2.0.0 or 2.0.1 is used to inspect Wi‑Fi traffic or open untrusted 802.11 capture files. Systems not running vulnerable Wireshark builds are not indicated as affected by the provided sources.

Exploitation context

The attacker must get a crafted 802.11 packet processed by vulnerable Wireshark. Sources describe denial of service through application crash. There is no KEV listing and no provided source confirms active exploitation.

Researcher notes

The public record identifies a buffer over-read in epan/dissectors/packet-ieee80211.c involving the Grouping subfield. The available sources do not provide CVSS, CWE, exploit-in-the-wild evidence, or broader affected product claims.

Mitigation direction

  • Upgrade Wireshark to version 2.0.2 or later.
  • Avoid opening untrusted 802.11 capture files until upgraded.
  • Follow Wireshark’s security advisory for version-specific guidance.

Validation and detection

  • Inventory installed Wireshark versions across analyst workstations and capture systems.
  • Confirm Wireshark is not version 2.0.0 or 2.0.1.
  • Identify workflows that inspect wireless captures or live 802.11 traffic.
  • Review crash reports involving Wireshark 802.11 packet analysis.
