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

2. No fixed release: DOWNGRADE to a release before 1.4sec (Debian / Ubuntu)

apt-cache madison inn sudo apt install inn=<VERSION_BEFORE_1.4sec> sudo apt-mark hold inn

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list inn sudo dnf downgrade inn-<VERSION_BEFORE_1.4sec> sudo dnf versionlock add inn

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.
