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.

Desbordamiento de búfer en NetRxPkt::ehdr_buf en hw/net/net_rx_pkt.c en QEMU (también conocido como Quick Emulator) cuando la característica VLANSTRIP está habilitada en el dispositivo vmxnet3, permite a atacantes remotos provocar una denegación de servicio (acceso fuera de límites y caída del proceso QEMU) a través de vectores relacionados con el decapado VLAN.
