CVE-2016-7907

Priority
Low
Description
The imx_fec_do_tx function in hw/net/imx_fec.c in QEMU (aka Quick Emulator)
does not properly limit the buffer descriptor count when transmitting
packets, which allows local guest OS administrators to cause a denial of
service (infinite loop and QEMU process crash) via vectors involving a
buffer descriptor with a length of 0 and crafted values in bd.flags.
