Source Facts

Wireshark announced 4.6.9 and 4.4.19 on 23 September, providing Windows and macOS installers and source code. Both branches include multiple security fixes, with separate links to full release notes.

The announcement links these fixes to a recent increase in SI-agent-assisted vulnerability reports; it does not equate the number of reports with exploited incidents. Organisations should use each version's security items and affected scope to assess update needs in their analysis environments.

Next Steps for Businesses / Editorial Observations

Investigation tools also process external data. Before opening packet captures from unknown sources, confirm the analysis tool version and workstation isolation arrangements.

Next steps you can take

  • Inventory the Wireshark branches used by security and network teams, including installed and portable versions.
  • Update your branch to the applicable fixed version, test common packet analysis workflows and retain original evidence files unchanged.
