Memory leak in the virgl_cmd_resource_unref function in hw/display/virtio-gpu-3d.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (host memory consumption) via a large number of VIRTIO_GPU_CMD_RESOURCE_UNREF commands sent without detaching the backing storage beforehand. Pérdida de memoria en la función virgl_cmd_resource_unref en hw/display/virtio-gpu-3d.c en QEMU (también conocido como Quick Emulator) permite a usuarios locales del SO invitado provocar una denegación de servicio (consumo de la memoria del host) a través de un número grande de comandos VIRTIO_GPU_CMD_RESOURCE_UNREF enviados sin desvincular el apoyo de almacenamiento de antemano. • http://git.qemu-project.org/?p=qemu.git%3Ba=commit%3Bh=5e8e3c4c75c199aa1017db816fca02be2a9f8798 http://www.openwall.com/lists/oss-security/2017/02/01/21 http://www.openwall.com/lists/oss-security/2017/02/02/16 http://www.securityfocus.com/bid/95993 https://bugzilla.redhat.com/show_bug.cgi?id=1418382 https://security.gentoo.org/glsa/201702-28 • CWE-401: Missing Release of Memory after Effective Lifetime •

https://notcve.org/view.php?id=CVE-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.
