tenable security center UPGRADE

Affected: >= 6.6.0 and <= 6.8.0

Fixed in: newer than 6.8.0

Safe to downgrade to: a release before 6.6.0

1. Check installed version

apt-cache policy security-center || rpm -q security-center || security-center --version

2. UPGRADE to newer than 6.8.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade security-center

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade security-center

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 6.6.0 (Debian / Ubuntu)

apt-cache madison security-center sudo apt install security-center=<VERSION_BEFORE_6.6.0> sudo apt-mark hold security-center

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

dnf --showduplicates list security-center sudo dnf downgrade security-center-<VERSION_BEFORE_6.6.0> sudo dnf versionlock add security-center

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.
