The maintenance update is above all security-relevant: it closes 28 vulnerabilities (WNPA-SEC-2026-64 to -91), nine of which can be triggered simply by opening a saved capture file.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most of the flaws involve crashes in protocol dissectors \u2013 the components Wireshark uses to break down individual protocols. Affected dissectors include those for RDP, Kerberos, SSH and several Bluetooth protocols. Because many of the bugs can be triggered via manipulated capture files, anyone who opens third-party captures should be especially careful.<\/p><div id=\"netgu-2142439592\" class=\"netgu-content
