dhtmlx pdf export module UPGRADE

Affected: >= 0.3.3 and < 0.7.6

Fixed in: 0.7.6

Safe to downgrade to: a release before 0.3.3

1. Check installed version

apt-cache policy pdf-export-module || rpm -q pdf-export-module || pdf-export-module --version

2. UPGRADE to 0.7.6 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade pdf-export-module

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 0.3.3 (Debian / Ubuntu)

apt-cache madison pdf-export-module sudo apt install pdf-export-module=<VERSION_BEFORE_0.3.3> sudo apt-mark hold pdf-export-module

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

dnf --showduplicates list pdf-export-module sudo dnf downgrade pdf-export-module-<VERSION_BEFORE_0.3.3> sudo dnf versionlock add pdf-export-module

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.
