+	  <p>Qemu emulator built with the AMD PC-Net II Ethernet Controller
+	    support is vulnerable to a heap buffer overflow flaw. While
+	    receiving packets in the loopback mode, it appends CRC code to the
+	    receive buffer. If the data size given is same as the receive buffer
+	    size, the appended CRC code overwrites 4 bytes beyond this
+	    's-&gt;buffer' array.</p>
+	  <p>A privileged(CAP_SYS_RAWIO) user inside guest could use this flaw
+	    to crash the Qemu instance resulting in DoS or potentially execute
+	    arbitrary code with privileges of the Qemu process on the host.</p>

+	  <p>The AMD PC-Net II emulator(hw/net/pcnet.c), while receiving packets
+	    from a remote host(non-loopback mode), fails to validate the
+	    received data size, thus resulting in a buffer overflow issue. It
+	    could potentially lead to arbitrary code execution on the host, with
+	    privileges of the Qemu process. It requires the guest NIC to have
