CVE-2017-13672

CVE-2017-13672 affects QEMU when built with VGA display emulator support. A local privileged user can trigger an out-of-bounds read during VGA display update, crashing the QEMU process and causing DoS. Public advisories confirm vga-related fix in qemu-kvm components (e.g., ALAS-2018-1034, CESA-20...

CVE-2017-13673

An assert failure issue was found in the VGA display emulator built into the Quick emulator QEMU. It could occur while updating graphics display, due to miscalculating region for dirty bitmap snapshot in split screen mode. A privileged user/process inside guest could use this flaw to crash the QE...

CVE-2017-13672

An out-of-bounds read access issue was found in the VGA display emulator built into the Quick emulator QEMU. It could occur while reading VGA memory to update graphics display. A privileged user/process inside guest could use this flaw to crash the QEMU process on the host resulting in denial of...

Qemu Denial of Service Vulnerability (CNVD-2017-30585)

QEMU aka Quick Emulator is a set of simulation processor software developed by French programmer Fabrice Bellard. The software is fast and cross-platform. A security vulnerability exists in the vga display update in QEMU versions 2.8.0 through 2.9.0. An attacker can exploit this vulnerability to...
