raphael assenat libmikmod DOWNGRADE

Affected: 3.1.12

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.1.12

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.1.12 (Debian / Ubuntu)

apt-cache madison libmikmod sudo apt install libmikmod=<VERSION_BEFORE_3.1.12> sudo apt-mark hold libmikmod

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

dnf --showduplicates list libmikmod sudo dnf downgrade libmikmod-<VERSION_BEFORE_3.1.12> sudo dnf versionlock add libmikmod

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.
