Description

Prasad J Pandit, Red Hat Product Security Team, reports: Qemu emulator built with the Virtual Network Device(virtio-net) support is vulnerable to a DoS issue. It could occur while receiving large packets over the tuntap/macvtap interfaces and when guest's virtio-net driver did not support big/mergeable receive buffers. An attacker on the local network could use this flaw to disable guest's networking by sending a large number of jumbo frames to the guest, exhausting all receive buffers and thus leading to a DoS situation.
