apache camel UPGRADE

Affected: >= 4.10.0 and < 4.14.8 · >= 4.15.0 and < 4.18.3 · >= 4.19.0 and < 4.21.0

Fixed in: 4.14.8, 4.18.3, 4.21.0

Safe to downgrade to: a release before 4.10.0

1. Check installed version

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

2. UPGRADE to 4.14.8 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade camel

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade camel

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 4.10.0 (Debian / Ubuntu)

apt-cache madison camel sudo apt install camel=<VERSION_BEFORE_4.10.0> sudo apt-mark hold camel

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

dnf --showduplicates list camel sudo dnf downgrade camel-<VERSION_BEFORE_4.10.0> sudo dnf versionlock add camel

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.
