vmware spring framework UPGRADE

Affected: < 5.3.48 · >= 6.1.0 and < 6.1.27 · >= 6.2.0 and < 6.2.18 · >= 7.0.0 and < 7.0.7

Fixed in: 5.3.48, 6.1.27, 6.2.18, 7.0.7

Safe to downgrade to: a release before 6.1.0

1. Check installed version

apt-cache policy spring-framework || rpm -q spring-framework || spring-framework --version

2. UPGRADE to 5.3.48 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade spring-framework

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-framework

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 6.1.0 (Debian / Ubuntu)

apt-cache madison spring-framework sudo apt install spring-framework=<VERSION_BEFORE_6.1.0> sudo apt-mark hold spring-framework

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

dnf --showduplicates list spring-framework sudo dnf downgrade spring-framework-<VERSION_BEFORE_6.1.0> sudo dnf versionlock add spring-framework

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.
