Package : wireshark-cli
Type : denial of service
Remote : Yes
Link : https://security.archlinux.org/AVG-1198
The package wireshark-cli before version 3.2.5-1 is vulnerable to

# pacman -Syu "wireshark-cli>=3.2.5-1"
The problem has been fixed upstream in version 3.2.5.
An infinite loop has been found in the GVCP dissector of Wireshark
before 3.2.5. It may be possible to make Wireshark consume excessive
