Mandriva Linux Security Advisory                         MDVSA-2010:040

Package : gnome-screensaver
Date    : February 17, 2010
Affected: 2010.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been discovered and corrected in
gnome-screensaver:

gnome-screensaver 2.28.0 does not resume adherence to its activation  settings after an inhibiting application becomes unavailable on the  session bus, which allows physically proximate attackers to access  an unattended workstation on which screen locking had been intended  (CVE-2009-4641).

gnome-screensaver before 2.28.2 allows physically proximate attackers  to bypass screen locking and access an unattended workstation by moving  the mouse position to an external monitor and then disconnecting that  monitor (CVE-2010-0414).

This update provides gnome-screensaver 2.28.3, which is not vulnerable  to these issues.
