Wireshark 4.6.9 has been released, according to a SANS ISC diary entry. The update fixes 19 vulnerabilities and 16 bugs, making it a significant maintenance and security release for the popular network protocol analyzer.
The diary does not break down which vulnerabilities are patched or their severity, but the volume of fixes suggests that users running earlier 4.6.x versions should upgrade promptly. As with most security updates, the safest practice is to install the latest version as soon as possible.
Because this is the only source, there is no independent confirmation of the specific flaws or their impact. Still, the official release notes from the Wireshark project would be the next place to look for detailed CVE listings and affected components.
