Affected: 1.12

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.12

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.12 (Debian / Ubuntu)

apt-cache madison chetcpasswd sudo apt install chetcpasswd=<VERSION_BEFORE_1.12> sudo apt-mark hold chetcpasswd

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.
