CVSS 3.0
9.1 criticalCVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:HCVE-2017-2615
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 copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host.
