Affected: 4.9.0 · 4.9.1 · 4.9.2 · 4.9.3 · 4.9.4 · 4.9.5

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.9.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 4.9.0 (Debian / Ubuntu)

apt-cache madison contendio sudo apt install contendio=<VERSION_BEFORE_4.9.0> sudo apt-mark hold contendio

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

dnf --showduplicates list contendio sudo dnf downgrade contendio-<VERSION_BEFORE_4.9.0> sudo dnf versionlock add contendio

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.
