主题: CVE request Qemu: display: cirrus_vga: a divide by zero in
cirrus_do_copy

   Hello,

Quick emulator(Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is
vulnerable to a divide by zero issue. It could occur while copying VGA data
when cirrus graphics mode was set to be VGA.

A privileged user inside guest could use this flaw to crash the Qemu process
instance on the host, resulting in DoS.

Thank you.
