Description

Buffer overflow in NetRxPkt::ehdr_buf in hw/net/net_rx_pkt.c in QEMU (aka Quick Emulator), when the VLANSTRIP feature is enabled on the vmxnet3 device, allows remote attackers to cause a denial of service (out-of-bounds access and QEMU process crash) via vectors related to VLAN stripping.
