Comment 1 Marian Rehak 2019-04-09 10:45:44 UTC
Created wireshark tracking bugs for this issue:

Affects: fedora-all [bug 1697943]

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.
