CVE-2017-9348: In Wireshark 2.2.0 to 2.2.6, the DOF dissector could read past the end of a buffer.

In Wireshark 2.2.0 to 2.2.6, the DOF dissector could read past the end of a buffer. This was addressed in epan/dissectors/packet-dof.c by validating a size value.

Security readout for executives and security teams

Plain-English summary

CVE-2017-9348 is a Wireshark parsing flaw in versions 2.2.0 through 2.2.6. The DOF dissector could read beyond a buffer while analyzing data. Business risk is mainly to analyst workstations or tooling that process untrusted captures, not a broadly exposed server service based on the supplied sources.

Executive priority

Treat this as a targeted remediation item for security operations and network-analysis environments. It does not have enough supplied evidence for emergency handling, but affected Wireshark versions are old and should be removed from operational use.

Technical view

The issue is an out-of-bounds read in Wireshark's DOF dissector. The source bundle states it was fixed in epan/dissectors/packet-dof.c by validating a size value. No CVSS, CWE, or detailed impact rating is provided in the supplied record.

Likely exposure

Exposure is likely limited to environments running Wireshark 2.2.0 to 2.2.6, especially where users inspect untrusted packet captures or traffic containing DOF data. The supplied affected-product metadata is incomplete and lists n/a values.

Exploitation context

The source bundle does not show CISA KEV listing or any cited evidence of active exploitation. Public references include Wireshark advisory, bug, commit, and oss-fuzz issue records, but no exploit-in-the-wild confirmation is supplied.

Researcher notes

The record identifies the vulnerable component and fix location, but lacks CVSS, CWE, detailed crash impact, and complete affected CPE data. Analysis should stay tied to Wireshark 2.2.0-2.2.6 and the DOF dissector size validation fix.

Mitigation direction

  • Upgrade affected Wireshark 2.2.0 to 2.2.6 installations using Wireshark vendor guidance.
  • Prioritize analyst workstations and capture-processing systems that handle untrusted files.
  • Limit opening untrusted captures on affected versions until remediation is complete.
  • Confirm the fix that validates the DOF size value is included.

Validation and detection

  • Inventory Wireshark versions across analyst endpoints, jump boxes, and tooling images.
  • Flag any Wireshark 2.2.0 through 2.2.6 installations for remediation.
  • Verify upgraded builds are no longer in the affected version range.
  • Check vendor advisory and package changelogs for CVE-2017-9348 coverage.
