vmware spring advanced message queuing protocol UPGRADE

Affected: < 2.4.19 · >= 3.2.0 and < 3.2.13 · >= 4.0.0 and < 4.0.4.1 · >= 4.1.0 and < 4.1.0.1

Fixed in: 2.4.19, 3.2.13, 4.0.4.1, 4.1.0.1

Safe to downgrade to: a release before 3.2.0

1. Check installed version

apt-cache policy spring-advanced-message-queuing-protocol || rpm -q spring-advanced-message-queuing-protocol || spring-advanced-message-queuing-protocol --version

2. UPGRADE to 2.4.19 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spring-advanced-message-queuing-protocol

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-advanced-message-queuing-protocol

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 3.2.0 (Debian / Ubuntu)

apt-cache madison spring-advanced-message-queuing-protocol sudo apt install spring-advanced-message-queuing-protocol=<VERSION_BEFORE_3.2.0> sudo apt-mark hold spring-advanced-message-queuing-protocol

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

dnf --showduplicates list spring-advanced-message-queuing-protocol sudo dnf downgrade spring-advanced-message-queuing-protocol-<VERSION_BEFORE_3.2.0> sudo dnf versionlock add spring-advanced-message-queuing-protocol

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.
