## Description

Xfce4-session 4.5.91 in Xfce does not lock the screen when the suspend or
hibernate button is pressed, which might make it easier for physically
proximate attackers to access an unattended laptop via a resume action, a
related issue to CVE-2010-2532. NOTE: there is no general agreement that
this is a vulnerability, because separate control over locking can be an
equally secure, or more secure, behavior in some threat environments

upstream does not intend to fix this in xfce4-session, but
rather via whatever power manager is installed.
