Descriptions

The vmxnet_tx_pkt_parse_headers function in hw/net/vmxnet_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (buffer over-read) by leveraging failure to check IP header length.

La función vmxnet_tx_pkt_parse_headers en hw/net/vmxnet_tx_pkt.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (sobre lectura del búfer) aprovechando el fallo para comprobar la longitud del encabezado IP.
