phystech dhcpcd DOWNGRADE

Affected: 1.3.17_pl2

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.3.17_pl2

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.3.17_pl2 (Debian / Ubuntu)

apt-cache madison dhcpcd sudo apt install dhcpcd=<VERSION_BEFORE_1.3.17_pl2> sudo apt-mark hold dhcpcd

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

dnf --showduplicates list dhcpcd sudo dnf downgrade dhcpcd-<VERSION_BEFORE_1.3.17_pl2> sudo dnf versionlock add dhcpcd

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.
