Qemu emulator built with the USB Net device emulation support is vulnerable to an integer overflow issue. It could occur while processing remote NDIS control message packets. As the incoming informationBufferOffset & Length combination could cross the integer range. A privileged user inside guest could use this flaw to leak host memory bytes to guest or crash the Qemu process instance resulting in DoS. https://lists.gnu.org/archive/html/qemu-devel/2016-02/msg03658.html https://bugzilla.redhat.com/show_bug.cgi?id=1303120 http://git.qemu.org/?p=qemu.git;a=commit;h=fe3c546c5ff2a6210f9a4d8561cc64051ca8603e
