Wireshark Analyzer 3.2.5

Authored by Gerald Combs | Site wireshark.org

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: A GVCP dissector infinite loop vulnerability has been addressed along with many other bug fixes.
