The Wireshark team has introduced version 4.4.9, a maintenance release for the globe’s most favored network protocol analyzer.
This update emphasizes stability and dependability, providing a series of crucial bug resolutions and boosting support for various existing protocols.
The new version is currently accessible on all supported platforms, including Windows, macOS, and Linux.
Wireshark, an essential resource for network administrators, security experts, and developers, facilitates an in-depth examination of network traffic. It is widely utilized for resolving network problems, scrutinizing security issues, and for educational purposes.
The initiative is hosted by the non-profit Wireshark Foundation, which depends on community contributions and sponsorships to continue its efforts in promoting protocol analysis education.
This recent release tackles multiple vulnerabilities and operational glitches. A significant correction addresses a crash in the SSH dissector (wnpa-sec-2025-03), a major concern for anyone evaluating secure shell traffic. Other notable fixes include:
- A faulty dissection of the RDM Product Detail List ID.
- Errors in SCCP LUDT segmentation decoding.
- An issue obstructing Ciscodump from starting captures on Cisco IOS devices.
- A malfunction with the visualization of the closing context tag in BACnet WritePropertyMultiple.
- A flaw in the LZ77 decoder that caused it to interpret a 16-bit length instead of the accurate 32-bit length.
While version 4.4.9 does not introduce support for any new protocols, it does encompass updates to several existing ones. Users will discover enhanced support for BACapp, LIN, MySQL, RDM, SABP, SCCP, sFlow, and SSH.
These improvements guarantee that Wireshark can more precisely interpret and exhibit data for these protocols, aligning with the latest standards and vendor-specific implementations.
The update does not comprise any new or updated capture file support or modifications to file format decoding. The development team’s concentration for this release has been firmly on refining the existing features and ensuring the tool remains stable and secure for its vast user base.
Network professionals are advised to upgrade to version 4.4.9 to take advantage of the recent fixes and protocol enhancements, ensuring a more secure and effective network analysis experience.
The Wireshark Foundation has officially unveiled the Wireshark Certified Analyst (WCA-101) certification, representing a notable leap forward in professional network analysis education.
