Description Prasad J Pandit 2017-05-19 06:58:41 EDT 
Qemu emulator built with the e1000e NIC emulation support is vulnerable to an
infinite loop issue. It could occur while processing data via transmit or
receive descriptors, provided the initial receive/transmit descriptor
head(TDH/RDH) is set outside the allocated descriptor buffer.

A privileged user inside guest could use this flaw to crash the Qemu instance
resulting in DoS.
