CVE-2009-4642

Publication date 11 February 2010

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

gnome-screensaver 2.26.1 relies on the gnome-session D-Bus interface to determine session idle time, even when an Xfce desktop such as Xubuntu or Mythbuntu is used, which allows physically proximate attackers to access an unattended workstation on which screen locking had been intended.

While it looks like a gnome-screensaver bug, for stable releases, this is an issue primarily for xfce, which doesn't use g-ss correctly. Going forward, gnome-session has been added to the g-ss package deps so that the issue is more obvious to integration attempts of g-ss.
