CVE-2020-13800

CVE-2020-13800 affects QEMU 4.2.0, specifically ati-vga in hw/display/ati.c. The vulnerability arises when a guest provides a crafted mm_index value, causing infinite recursion in ati_mm_read/ati_mm_write. The described impact indicates a crash (DoS-like behavior) of the QEMU component, not neces...

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.
