Affected: < 8.7.4 · >= 8.8 and < 8.8.2

Fixed in: 8.7.4, 8.8.2

dnf --showduplicates list ws-ftp-server sudo dnf downgrade ws-ftp-server-<VERSION_BEFORE_8.8> sudo dnf versionlock add ws-ftp-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.
