Affected: < 2.2.1 · >= 3.0.0 and < 3.5.1

Fixed in: 2.2.1, 3.5.1

Safe to downgrade to: a release before 3.0.0

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 3.0.0 (Debian / Ubuntu)

apt-cache madison master-quiz sudo apt install master-quiz=<VERSION_BEFORE_3.0.0> sudo apt-mark hold master-quiz

dnf --showduplicates list master-quiz sudo dnf downgrade master-quiz-<VERSION_BEFORE_3.0.0> sudo dnf versionlock add master-quiz

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.
