Descriptions
rom_copy() in hw/core/loader.c in QEMU 4.0 and 4.1.0 does not validate the relationship between two addresses, which allows attackers to trigger an invalid memory copy operation.
La función rom_copy() en el archivo hw/core/loader.c en QEMU versión 4.0 y versión 4.1.0, no comprueba la relación entre dos direcciones, lo que permite a atacantes activar una operación de copia de memoria no válida
An out-of-bound write access flaw was found in the way QEMU loads ROM contents at boot time. This flaw occurs in the rom_copy() routine while loading the contents of a 32-bit -kernel image into memory. Running an untrusted -kernel image may load contents at arbitrary memory locations, potentially leading to code execution with the privileges of the QEMU process.
