fasterxml jackson-databind UPGRADE

Affected: >= 2.0.0 and < 2.6.7.3 · >= 2.7.0 and < 2.8.11.5 · >= 2.9.0 and < 2.9.10

Fixed in: 2.6.7.3, 2.8.11.5, 2.9.10

Safe to downgrade to: a release before 2.0.0

1. Check installed version

apt-cache policy jackson-databind || rpm -q jackson-databind || jackson-databind --version

2. UPGRADE to 2.6.7.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade jackson-databind

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade jackson-databind

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 jackson-databind sudo apt install jackson-databind=<VERSION_BEFORE_2.0.0> sudo apt-mark hold jackson-databind

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

dnf --showduplicates list jackson-databind sudo dnf downgrade jackson-databind-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add jackson-databind

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.
