Qinghao Tang of QIHU 360 Inc. discovered a heap buffer overflow flaw in
the NE2000 NIC emulation. A privileged guest user could use this flaw to
mount a denial of service (QEMU process crash), or potentially to execute
arbitrary code on the host with the privileges of the hosting QEMU
process. (CVE-2015-5279)

A flaw has been discovered in the QEMU emulator built with Virtual Network
Device(virtio-net) support. If the guest's virtio-net driver did not
support big or mergeable receive buffers, an issue could occur while
receiving large packets over the tuntap/ macvtap interfaces. An attacker
on the local network could use this flaw to disable the guest's
networking, the user could send a large number of jumbo frames to the
guest, which could exhaust all receive buffers, and lead to a denial of
service. (CVE-2015-7295)");
