Description
The vga_draw_text function in Qemu allows local OS guest privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging improper memory address validation.
An out-of-bounds read access issue was found in the VGA emulator of QEMU. It could occur in vga_draw_text routine, while updating display area for a vnc client. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS.
