macromedia coldfusion server DOWNGRADE

Affected: 4.x

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.x

1. Check installed version

apt-cache policy coldfusion-server || rpm -q coldfusion-server || coldfusion-server --version

2. No fixed release: DOWNGRADE to a release before 4.x (Debian / Ubuntu)

apt-cache madison coldfusion-server sudo apt install coldfusion-server=<VERSION_BEFORE_4.x> sudo apt-mark hold coldfusion-server

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

dnf --showduplicates list coldfusion-server sudo dnf downgrade coldfusion-server-<VERSION_BEFORE_4.x> sudo dnf versionlock add coldfusion-server

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.
