Permissions, Privileges, and Access Controls
** DISPUTED ** 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.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
