Wireshark is a GTK+-based network protocol analyzer that lets you capture and interactively browse the contents of network frames. The goal of the project is to create a commercial-quality analyzer for Unix and Win32 and to give Wireshark features that are missing from closed-source sniffers. This is the source code release.

Changes: An unsafe url opening vulnerability has been addressed. Updated protocol support for ASTERIX, Frame Relay, GQUIC, NTP, NVMe Fabrics RDMA, S7COMM, and SIP. 8 bugs have been fixed.
