Affected: 0.4 · 0.4.1 · 0.5 · 0.5.1 · 0.6

1. Check installed version

apt-cache policy apache-gallery || rpm -q apache-gallery || apache-gallery --version

dnf --showduplicates list apache-gallery sudo dnf downgrade apache-gallery-<VERSION_BEFORE_0.4> sudo dnf versionlock add apache-gallery

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.
