    It was discovered that the acpi-support update for DSA-2984-1 would make a laptop's power button forcibly shut the system down, instead of triggering the configured action (usually suspend to RAM). This only affects systems using the gnome-settings-daemon.

    Package        : acpi-support
    Debian Bug     : 755969
    
    It was discovered that the acpi-support update for DSA-2984-1 would
    make a laptop's power button forcibly shut the system down, instead of
    triggering the configured action (usually suspend to RAM). This only
    affects systems using the gnome-settings-daemon.
    
    For reference, the original advisory follows.
    
    CESG discovered a root escalation flaw in the acpi-support package. An
    unprivileged user can inject the DBUS_SESSION_BUS_ADDRESS environment
    variable to run arbitrary commands as root user via the policy-funcs
    script.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 0.140-5+deb7u2.
    
    For the testing distribution (jessie), this problem will be fixed soon.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 0.142-3.
    
    We recommend that you upgrade your acpi-support packages.
