A heap buffer overflow flaw was found in QEMU’s Cirrus CLGD 54xx VGA
emulator’s VNC display driver support before 2.9; the issue could occur
when a VNC client attempted to update its display after a VGA operation is
performed by a guest. A privileged user/process inside a guest could use
this flaw to crash the QEMU process or, potentially, execute arbitrary code
on the host with privileges of the QEMU process.
