vmware spring security UPGRADE

Affected: >= 7.0.0 and < 7.0.5.1

Fixed in: 7.0.5.1

Safe to downgrade to: a release before 7.0.0

1. Check installed version

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

2. UPGRADE to 7.0.5.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade spring-security

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 7.0.0 (Debian / Ubuntu)

apt-cache madison spring-security sudo apt install spring-security=<VERSION_BEFORE_7.0.0> sudo apt-mark hold spring-security

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

dnf --showduplicates list spring-security sudo dnf downgrade spring-security-<VERSION_BEFORE_7.0.0> sudo dnf versionlock add spring-security

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.
