nema dicom standard UPGRADE

Affected: >= 1995 and <= 2019b

Fixed in: newer than 2019b

Safe to downgrade to: a release before 1995

1. Check installed version

apt-cache policy dicom-standard || rpm -q dicom-standard || dicom-standard --version

2. UPGRADE to newer than 2019b (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade dicom-standard

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade dicom-standard

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 1995 (Debian / Ubuntu)

apt-cache madison dicom-standard sudo apt install dicom-standard=<VERSION_BEFORE_1995> sudo apt-mark hold dicom-standard

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

dnf --showduplicates list dicom-standard sudo dnf downgrade dicom-standard-<VERSION_BEFORE_1995> sudo dnf versionlock add dicom-standard

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.
