Name of the Vulnerable Software and Affected Versions gnome-screensaver version 2.26.1

Description The issue allows physically proximate attackers to access an unattended workstation where screen locking was intended, due to gnome-screensaver relying on the gnome-session D-Bus interface to determine session idle time. This occurs even when using an Xfce desktop, such as Xubuntu or Mythbuntu.

Recommendations For gnome-screensaver version 2.26.1, consider disabling the use of the gnome-session D-Bus interface for determining session idle time as a temporary workaround, until a patch is available. Restrict access to the workstation to minimize the risk of exploitation.
