CVE-2018-19627: In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the IxVeriWave file parser could crash.

In Wireshark 2.6.0 to 2.6.4 and 2.4.0 to 2.4.10, the IxVeriWave file parser could crash. This was addressed in wiretap/vwr.c by adjusting a buffer boundary.

Security readout for executives and security teams

Plain-English summary

CVE-2018-19627 is a Wireshark denial-of-service issue. A malformed IxVeriWave file could make affected Wireshark versions crash when parsed. This is most relevant where analysts open untrusted capture files, not as a broad internet-exposed server risk.

Executive priority

Address during normal vulnerability remediation, with higher urgency for SOC or forensic teams that open untrusted capture files. The business impact is likely disruption of analysis tools rather than direct system compromise based on available evidence.

Technical view

Wireshark 2.6.0 through 2.6.4 and 2.4.0 through 2.4.10 had an IxVeriWave parser crash in wiretap/vwr.c. The fix adjusted a buffer boundary. The source bundle does not provide CVSS, CWE, or evidence of code execution.

Likely exposure

Exposure is likely limited to endpoints or analysis systems running affected Wireshark versions and opening IxVeriWave files. Organizations that do not use Wireshark, do not parse IxVeriWave files, or run newer fixed versions have lower exposure.

Exploitation context

The source bundle includes an Exploit-DB reference, so public exploit information exists. KEV is false, and the provided sources do not state active exploitation in the wild. Treat this as user-assisted parser crash risk.

Researcher notes

Focus validation on file parsing workflows and exact Wireshark versions. The available description points to a buffer-boundary correction in wiretap/vwr.c, but does not provide CVSS, CWE, or confirmed impact beyond crash.

Mitigation direction

  • Upgrade Wireshark beyond affected 2.6.x and 2.4.x versions using vendor guidance.
  • Apply relevant distribution security updates, such as Debian DSA-4359 where applicable.
  • Restrict opening untrusted IxVeriWave files on affected analysis workstations.
  • Check downstream vendor advisories if Wireshark is embedded or packaged by another product.

Validation and detection

  • Inventory Wireshark versions on analyst workstations, servers, and packaged toolchains.
  • Confirm no systems run Wireshark 2.6.0-2.6.4 or 2.4.0-2.4.10.
  • Review package manager records for applied Wireshark security updates.
  • Verify controls for handling untrusted capture files in security operations workflows.
