Fixed in: no fixed release known

Safe to downgrade to: a release before 1.8.4

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.8.4 (Debian / Ubuntu)

apt-cache madison gdlib sudo apt install gdlib=<VERSION_BEFORE_1.8.4> sudo apt-mark hold gdlib

dnf --showduplicates list gdlib sudo dnf downgrade gdlib-<VERSION_BEFORE_1.8.4> sudo dnf versionlock add gdlib

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

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