Affected: 1.3.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.3.1

1. Check installed version

apt-cache policy srvx || rpm -q srvx || srvx --version

2. No fixed release: DOWNGRADE to a release before 1.3.1 (Debian / Ubuntu)

apt-cache madison srvx sudo apt install srvx=<VERSION_BEFORE_1.3.1> sudo apt-mark hold srvx

After downgrade

Restart the service, and keep the package held until a fixed release ships.
