mozilla 0din scanner UPGRADE

Affected: >= 1.0.0 and < 1.4.1

Fixed in: 1.4.1

Safe to downgrade to: a release before 1.0.0

1. Check installed version

apt-cache policy 0din-scanner || rpm -q 0din-scanner || 0din-scanner --version

2. UPGRADE to 1.4.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade 0din-scanner

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.0.0 (Debian / Ubuntu)

apt-cache madison 0din-scanner sudo apt install 0din-scanner=<VERSION_BEFORE_1.0.0> sudo apt-mark hold 0din-scanner

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list 0din-scanner sudo dnf downgrade 0din-scanner-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add 0din-scanner

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.
