Timeline

zinf zinf DOWNGRADE
Affected: 2.2.1
Fixed in: no fixed release known
Safe to downgrade to: a release before 2.2.1
1. Check installed version
apt-cache policy zinf || rpm -q zinf || zinf --version
2. No fixed release: DOWNGRADE to a release before 2.2.1 (Debian / Ubuntu)
apt-cache madison zinf sudo apt install zinf=<VERSION_BEFORE_2.2.1> sudo apt-mark hold zinf
2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list zinf sudo dnf downgrade zinf-<VERSION_BEFORE_2.2.1> sudo dnf versionlock add zinf
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.
debian debian linux MITIGATE
Affected: 3.0
Fixed in: no fixed release known
Safe to downgrade to: a release before 3.0
