Affected: >= 2.5.3 and < 5.3.0

Fixed in: 5.3.0

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 2.5.3 (Debian / Ubuntu)

apt-cache madison munkireport sudo apt install munkireport=<VERSION_BEFORE_2.5.3> sudo apt-mark hold munkireport

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
