Affected: >= 5.0 and < 5.5.5.2811

Fixed in: 5.5.5.2811

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 5.0 (Debian / Ubuntu)

apt-cache madison eviden-cardos-api sudo apt install eviden-cardos-api=<VERSION_BEFORE_5.0> sudo apt-mark hold eviden-cardos-api

Downgrade risk
