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.
