Affected: 4.5.5

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.5.5

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 4.5.5 (Debian / Ubuntu)

apt-cache madison ibos sudo apt install ibos=<VERSION_BEFORE_4.5.5> sudo apt-mark hold ibos

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

dnf --showduplicates list ibos sudo dnf downgrade ibos-<VERSION_BEFORE_4.5.5> sudo dnf versionlock add ibos

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.
