dropwizard dropwizard validation UPGRADE

Affected: < 1.3.21 · >= 2.0.0 and < 2.0.3

Fixed in: 1.3.21, 2.0.3

Safe to downgrade to: a release before 2.0.0

1. Check installed version

apt-cache policy dropwizard-validation || rpm -q dropwizard-validation || dropwizard-validation --version

2. UPGRADE to 1.3.21 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade dropwizard-validation

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade dropwizard-validation

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.0.0 (Debian / Ubuntu)

apt-cache madison dropwizard-validation sudo apt install dropwizard-validation=<VERSION_BEFORE_2.0.0> sudo apt-mark hold dropwizard-validation

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list dropwizard-validation sudo dnf downgrade dropwizard-validation-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add dropwizard-validation

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.
