Description Agostino Sarubbo gentoo-dev 2016-09-09 13:25:11 UTC
From ${URL} :

Quick Emulator(Qemu) built with the VMware-SVGA "chipset" emulation support is 
vulnerable to an OOB stack memory write issue. It could occur while processing 
VGA commands in 'vmsvga_fifo_run' routine.

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

Upstream fix:
