Description Prasad J Pandit 2017-07-19 02:13:14 EDT 
Quick emulator(Qemu) built with the BOOTP/DHCP Server support is vulnerable
to an OOB read issue. It could occur while parsing the DHCP options and vendor
extensions options sent by a client.

A user/process could use this flaw to potentially crash the Qemu process on
the host resulting in DoS.
