Affected: >= 8.1.0.0 and <= 8.1.26

Fixed in: newer than 8.1.26

Safe to downgrade to: a release before 8.1.0.0

1. Check installed version

apt-cache policy spectrum-protect-server || rpm -q spectrum-protect-server || spectrum-protect-server --version

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 8.1.0.0 (Debian / Ubuntu)

apt-cache madison spectrum-protect-server sudo apt install spectrum-protect-server=<VERSION_BEFORE_8.1.0.0> sudo apt-mark hold spectrum-protect-server

dnf --showduplicates list spectrum-protect-server sudo dnf downgrade spectrum-protect-server-<VERSION_BEFORE_8.1.0.0> sudo dnf versionlock add spectrum-protect-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.
