Affected: < 3.6.1 · >= 4.0.0 and < 4.0.3

Fixed in: 3.6.1, 4.0.3

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 4.0.0 (Debian / Ubuntu)

apt-cache madison plexus-utils sudo apt install plexus-utils=<VERSION_BEFORE_4.0.0> sudo apt-mark hold plexus-utils
