Descriptions
Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used.
Qemu tiene un desbordamiento de búfer en rtl8139_do_receive en hw/net/rtl8139.c debido a que se emplea un tipo de datos de enteros incorrecto.
An integer overflow issue was found in the RTL8139 NIC emulation in QEMU. It could occur while receiving packets over the network if the size value is greater than INT_MAX. Such overflow would lead to stack buffer overflow issue. A user inside guest could use this flaw to crash the QEMU process, resulting in DoS scenario.
