Wireshark 3.0.5 has been released with the new Qt version and fix for other vulnerabilities. The Qt is the library used in Wireshark to build the UI.
The Wireshark is the famous protocol analyzer tool used for protocol analysis, troubleshooting, protocol development, and education.
It is used by network administrators to troubleshoot network and by the security analyst to examine the packets. It is a widely used tool in organizations.
With the release the windows installers ships with Qt 5.12.5, previously it was Qt 5.12.4. Before upgrading to the new version, Wireshark team recommends to manually uninstall Npcap 0.994 or 0.995 if it is installed.
If the Npcap was not installed, it may results in a possible crash while upgrading. More details about Npcap bugs can be found here and here.
Wireshark also provided steps to manually uninstall Npcap
- Open a command or PowerShell prompt as Administrator and run sc.exe config npcap start=disabled.
- Run sc.exe config npf start=disabled. This will fail if WinPcap compatibility mode isn’t enabled, but is otherwise harmless.
- Reboot (optional).
- Open “Programs and Features” in the Control Panel or “Apps & features” in Settings and uninstall Npcap.
- Open “Device Manager” (devmgmt.msc) in the Control Panel and expand the “Network adapters” section. Uninstall each “Npcap Loopback Adapter” that you find.
