CVE-2016-10894

xtrlock through 2.10 does not block multitouch events. Consequently, an
attacker at a locked screen can send input to (and thus control) various
programs such as Chromium via events such as pan scrolling, “pinch and
zoom” gestures, or even regular mouse clicks (by depressing the touchpad
once and then clicking with a different finger).
