juzaweb cms UPGRADE

Affected: >= 3.4 and <= 3.4.2

Fixed in: newer than 3.4.2

Note

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

dnf --showduplicates list cms sudo dnf downgrade cms-<VERSION_BEFORE_3.4> sudo dnf versionlock add cms

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.
