Descriptions
A flaw was found in dpdk in versions before 18.11.10 and before 19.11.5. A complete lack of validation of attacker-controlled parameters can lead to a buffer over read. The results of the over read are then written back to the guest virtual machine memory. This vulnerability can be used by an attacker in a virtual machine to read significant amounts of host memory. The highest threat from this vulnerability is to data confidentiality and system availability.
Se encontró un fallo en dpdk en versiones anteriores a 18.11.10 y anteriores a 19.11.5. Una falta total de comprobación de los parámetros controlados por el atacante puede conllevar a una lectura excesiva del búfer. Los resultados de la lectura excesiva se vuelven a escribir en la memoria de la máquina virtual invitada. Un atacante puede utilizar esta vulnerabilidad en una máquina virtual para leer cantidades significativas de memoria del host. La mayor amenaza de esta vulnerabilidad es la confidencialidad de los datos y la disponibilidad del sistema
