https://notcve.org/view.php?id=CVE-2016-9921
Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to a divide by zero issue. It could occur while copying VGA data when cirrus graphics mode was set to be VGA. A privileged user inside guest could use this flaw to crash the Qemu process instance on the host, resulting in DoS. Quick emulator (Qemu) construido con el soporte Cirrus CLGD 54xx VGA Emulator es vulnerable a un problema de división por cero. Podría ocurrir mientras se copian datos VGA cuando el modo de gráficos cirrus estaba configurado para ser VGA. • http://www.openwall.com/lists/oss-security/2016/12/09/1 http://www.securityfocus.com/bid/94803 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://lists.debian.org/debian-lts-announce/2018/09/msg00007.html https://security.gentoo.org/glsa/201701-49 https://access.redhat.com/security/cve/CVE-2016-9921 https://bugzilla.redhat.com/show_bug.cgi?id=1334398 • CWE-369: Divide By Zero •

https://notcve.org/view.php?id=CVE-2016-7466
Memory leak in the usb_xhci_exit function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator), when the xhci uses msix, allows local guest OS administrators to cause a denial of service (memory consumption and possibly QEMU process crash) by repeatedly unplugging a USB device. Fuga de memoria en la función usb_xhci_exit en hw/usb/hcd-xhci.c en QEMU (también conocido como Quick Emulator), cuando el xhci utiliza msix, permite a administradores locales del SO invitado provocar una denegación de servicio (consumo de memoria y posible caída del proceso QEMU) desconectando repetidamente un dispositivo USB. A memory-leak flaw was found in the Quick Emulator(QEMU) built with USB xHCI controller emulation support. The flaw could occur while doing a USB-device unplug operation. Unplugging the device repeatedly resulted in leaking host memory, which affected other services on the host. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=b53dd4495ced2432a0b652ea895e651d07336f7e http://lists.opensuse.org/opensuse-updates/2016-12/msg00140.html http://www.openwall.com/lists/oss-security/2016/09/19/8 http://www.openwall.com/lists/oss-security/2016/09/20/3 http://www.securityfocus.com/bid/93029 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://lists.gnu.org/archive/html/qemu-devel/2016-09/msg02773.html https:&#x • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-772: Missing Release of Resource after Effective Lifetime •
