phpmyadmin phpmyadmin UPGRADE

Affected: >= 4.9.0 and < 4.9.8 · >= 5.1.0 and < 5.1.2

Fixed in: 4.9.8, 5.1.2

Safe to downgrade to: a release before 4.9.0

1. Check installed version

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

2. UPGRADE to 4.9.8 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 4.9.0 (Debian / Ubuntu)

apt-cache madison phpmyadmin sudo apt install phpmyadmin=<VERSION_BEFORE_4.9.0> sudo apt-mark hold phpmyadmin

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

dnf --showduplicates list phpmyadmin sudo dnf downgrade phpmyadmin-<VERSION_BEFORE_4.9.0> sudo dnf versionlock add phpmyadmin

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.
