Descriptions

Heap-based buffer overflow in the PCNET controller in QEMU allows remote attackers to execute arbitrary code by sending a packet with TXSTATUS_STARTPACKET set and then a crafted packet with TXSTATUS_DEVICEOWNS set.

Desbordamiento de buffer basado en memoria dinámica en el controlador PCNET en QEMU permite a atacantes remotos ejecutar código arbitrario mediante el envío de un paquete con el juego TXSTATUS_STARTPACKET y posteriormente un paquete manipulado con el juego TXSTATUS_DEVICEOWNS.

A flaw was found in the way QEMU's AMD PCnet Ethernet emulation handled multi-TMD packets with a length above 4096 bytes. A privileged guest user in a guest with an AMD PCNet ethernet card enabled could potentially use this flaw to execute arbitrary code on the host with the privileges of the hosting QEMU process.
