zend zend framework UPGRADE

Affected: < 1.12.9 · >= 2.2.0 and < 2.2.8 · >= 2.3.0 and < 2.3.3

Fixed in: 1.12.9, 2.2.8, 2.3.3

Safe to downgrade to: a release before 2.2.0

1. Check installed version

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

2. UPGRADE to 1.12.9 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade zend-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 2.2.0 (Debian / Ubuntu)

apt-cache madison zend-framework sudo apt install zend-framework=<VERSION_BEFORE_2.2.0> sudo apt-mark hold zend-framework

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

dnf --showduplicates list zend-framework sudo dnf downgrade zend-framework-<VERSION_BEFORE_2.2.0> sudo dnf versionlock add zend-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.
