A heap buffer overflow flaw was found in QEMU’s Cirrus CLGD 54xx VGA emulator’s VNC display driver support; 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.
