CVE-2017-2615
Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.65%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
