Calendar Grey December 12, 2025
Dist Fedora Esm H88
Latest Fedora 43 wireshark update 4.6.1 addresses critical threats and recommends system upgrade procedures for users.
New version 4.6.1

Summary

Wireshark allows you to examine protocol data stored in files or as it is

captured from wired or wireless (WiFi or Bluetooth) networks, USB devices,

and many other sources. It supports dozens of protocol capture file formats

and understands more than a thousand protocols.

It has many powerful features including a rich display filter language

and the ability to reassemble multiple protocol packets in order to, for

example, view a complete TCP stream, save the contents of a file which was

transferred over HTTP or CIFS, or play back an RTP audio stream.

Update Information:

New version 4.6.1. Beware of the move of files from /usr/lib64/wireshark/extcap/ to /usr/libexec/wireshark/extcap. Any custom user scripts should be moved too.
