## 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
