From ${URL} : Quick emulator(Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt functions cirrus_bitblt_rop_fwd_transp_ and/or cirrus_bitblt_rop_fwd_. A privileged user inside guest could use this flaw to crash the Qemu process resulting in DoS.
