netbsd ftpd DOWNGRADE

Affected: 1.5 · 1.5.1 · 1.5.2 · 1.5.3 · 1.6

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.5

1. Check installed version

apt-cache policy ftpd || rpm -q ftpd || ftpd --version

2. No fixed release: DOWNGRADE to a release before 1.5 (Debian / Ubuntu)

apt-cache madison ftpd sudo apt install ftpd=<VERSION_BEFORE_1.5> sudo apt-mark hold ftpd

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list ftpd sudo dnf downgrade ftpd-<VERSION_BEFORE_1.5> sudo dnf versionlock add ftpd

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.
