Wireshark 4.0.8 Release: What’s New!

Wireshark released the latest release note for 4.0.8 on its official page regarding bug fixes that have been detected earlier and updated protocol support.

A network protocol analyzer, Wireshark captures packets from a network connection, providing insightful network analysis.

The end of support for 32-bit Windows files has been planned for Wireshark 4.0 and later.

For those who need to use Wireshark on that platform are recommended to use the current 3.6 edition.

Additionally the users who have updated their macOS to macOS 13 from an earlier version may require opening the “Uninstall ChmodBPF” package and running “Install ChmodBPF” to reset the ChmodBPF Launch Daemon for using wireshark.

• Due to a failure in validating the length provided by an attacker-crafted CP2179 packet, Wireshark versions 2.0.0 through 4.0.7, by default, are susceptible to a divide by zero allowing for a denial of service attack. [CVE-2023-2906] appears to be an instance of [CWE-369].
