Affected: 3.2.0 · 3.3.0 · 3.3.1 · 3.3.2 · 3.3.2.1 · 3.3.3 · 3.3.4 · 3.3.4.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.2.0

1. Check installed version

apt-cache policy ruby-agent || rpm -q ruby-agent || ruby-agent --version

2. No fixed release: DOWNGRADE to a release before 3.2.0 (Debian / Ubuntu)

apt-cache madison ruby-agent sudo apt install ruby-agent=<VERSION_BEFORE_3.2.0> sudo apt-mark hold ruby-agent

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

dnf --showduplicates list ruby-agent sudo dnf downgrade ruby-agent-<VERSION_BEFORE_3.2.0> sudo dnf versionlock add ruby-agent

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.
