Hello,An out-of-bounds access issue was found in the ati-vga emulator of the QEMU. It could occur while reading PCI configuration bytes via ati_mm_read routine, if the address sent by a guest is towards an end of the PCI configuration space. A guest user/process may use this flaw to crash the QEMU process resulting in DoS scenario.
