tanium enforce UPGRADE

Affected: >= 2.9.0 and < 2.9.718 · >= 2.10.0 and < 2.10.760 · >= 3.0.0 and < 3.0.346

Fixed in: 2.9.718, 2.10.760, 3.0.346

Safe to downgrade to: a release before 2.9.0

1. Check installed version

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

2. UPGRADE to 2.9.718 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade enforce

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade enforce

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 2.9.0 (Debian / Ubuntu)

apt-cache madison enforce sudo apt install enforce=<VERSION_BEFORE_2.9.0> sudo apt-mark hold enforce

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

dnf --showduplicates list enforce sudo dnf downgrade enforce-<VERSION_BEFORE_2.9.0> sudo dnf versionlock add enforce

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.
