  "details" : [ "Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used.", "An integer overflow issue was found in the AMD PC-Net II NIC emulation in QEMU. It could occur while receiving packets, if the size value was greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. A user inside guest could use this flaw to crash the QEMU process resulting in DoS." ],
