CVE-2020-13800

An infinite recursion flaw was found in the ati-vga emulator of the QEMU. The issue occurs in atimmread/write routines while accessing VGA registers, for certain values of the 'mmindex' variable. This flaw allows a guest user or process to crash the QEMU process, resulting in a denial of service...

CVE-2020-13791

An out-of-bounds access flaw was found in the ati-vga emulator of the QEMU. The issue occurs while reading PCI configuration bytes via the atimmread routine if the address sent by a guest is towards an end of the PCI configuration space. This flaw allows a guest user or process to crash the QEMU...

CVE-2019-20808

An out-of-bounds read flaw was found in the ATI VGA implementation of the QEMU emulator. This flaw occurs in the aticursordefine routine while handling MMIO write operations through atimmwrite callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of...
