Comment 3 Riccardo Schirone 2019-05-15 14:31:16 UTC 
Statement:

This issue did not affect the versions of wireshark as shipped with Red Hat Enterprise Linux 8 as they did not include support for TSDNS (TeamSpeak3 DNS) packet disassembly.
Comment 4 Riccardo Schirone 2019-05-16 09:19:29 UTC 
A invalid memory read in ws_basestrtou64() function in wireshark/wsutil/strtoi.c make wireshark crash when analyzing TSDNS packets.
