Does this matter?
Lower severity and a low EPSS score (3.04%). Track it; it rarely justifies an emergency change on its own.
Description
An out-of-bounds memory access issue was found in Quick Emulator (QEMU) before 1.7.2 in the VNC display driver. This flaw could occur while refreshing the VNC display surface area in the 'vnc_refresh_server_surface'. A user inside a guest could use this flaw to crash the QEMU process.
