  "details" : [ "Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop.", "An integer overflow issue was found in the VNC display driver of the QEMU emulator, which could be used by a privileged guest user to create a denial of service attack. The overflow occurred when processing a CLIENT_CUT_TEXT message with too large a payload size. The integer overflow led to an infinite loop inside the VNC driver, eventually crashing the QEMU process on the host." ],
