Description Prasad J Pandit 2017-10-12 10:52:15 UTC
Quick emulator(Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is
vulnerable to an out-of-bounds write access issues. It could occur while writing
to VGA memory via mode4and5 write functions.

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