CVE-2018-20839 Open this link in a new tabHow to fix?
There is no fixed version for Debian:8 systemd.
NVD Description
Note: Versions mentioned in the description apply only to the upstream systemd package and not the systemd package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
systemd 242 changes the VT1 mode upon a logout, which allows attackers to read cleartext passwords in certain circumstances, such as watching a shutdown, or using Ctrl-Alt-F1 and Ctrl-Alt-F2. This occurs because the KDGKBMODE (aka current keyboard mode) check is mishandled.
