Descriptions
Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode.
Desbordamiento de búfer basado en memoria dinámica (heap) en la función pcnet_receive en hw/net/pcnet.c en QEMU permite que administradores del sistema operativo invitados provoquen una denegación de servicio (cierre inesperado de la instancia) o que puedan ejecutar código arbitrario mediante una serie de paquetes en modo de bucle invertido.
A heap-based buffer overflow flaw was discovered in the way QEMU's AMD PC-Net II Ethernet Controller emulation
received certain packets in loopback mode. A privileged user (with the CAP_SYS_RAWIO capability) inside a guest could use this flaw to crash the host QEMU process (resulting in denial of service) or, potentially, execute arbitrary code with privileges of the host QEMU process.
