Summary
Wireshark versions 4.4.0 through 4.4.14 and 4.6.0 through 4.6.4 can crash if they examine network data that uses the BEEP protocol. This could cause the program to close unexpectedly, interrupting any monitoring or analysis work. Update Wireshark to a later version or avoid analyzing BEEP traffic until the fix is applied.
