Affected: 1.0 · 1.1 · 1.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.0 (Debian / Ubuntu)

apt-cache madison chuid sudo apt install chuid=<VERSION_BEFORE_1.0> sudo apt-mark hold chuid

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

dnf --showduplicates list chuid sudo dnf downgrade chuid-<VERSION_BEFORE_1.0> sudo dnf versionlock add chuid

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.
