Mandriva Linux Security Advisory 2015-162 - Clemens Fries reported that, when using Cinnamon, it was possible to bypass the screensaver lock. An attacker with physical access to the machine could use this flaw to take over the locked desktop session. This was fixed by including a patch for the root cause of the issue in gtk+3.0, which came from the implementation of popup menus in GtkWindow. This update also includes other patches from upstream to fix bugs affecting GtkFileChooser and GtkSpinButton, and a crash related to clipboard handling.
