The get_cmd function in hw/scsi/esp.c in the 53C9X Fast SCSI Controller (FSC) support in QEMU does not properly check DMA length, which allows local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via unspecified vectors, involving an SCSI command. La función get_cmd en hw/scsi/esp.c en el soporte 53C9X Fast SCSI Controller (FSC) en QEMU no comprueba correctamente la extensión DMA, lo que permite a administradores locales invitados del sistema operativo provocar una denegación del servicio (escritura fuera de rango y caída del proceso QEMU) a través de vectores no especificados, involucrando un comando SCSI. • http://www.openwall.com/lists/oss-security/2016/05/19/4 http://www.securityfocus.com/bid/90762 http://www.ubuntu.com/usn/USN-3047-1 http://www.ubuntu.com/usn/USN-3047-2 https://bugzilla.redhat.com/show_bug.cgi?id=1337505 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg03274.html https://security.gentoo.org/glsa/201609-01 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 6.5EPSS: 0%CPEs: 26EXPL: 0CVE-2016-4020 – Qemu: i386: leakage of stack memory to guest in kvmvapic.c
https://notcve.org/view.php?id=CVE-2016-4020
The patch_instruction function in hw/i386/kvmvapic.c in QEMU does not initialize the imm32 variable, which allows local guest OS administrators to obtain sensitive information from host stack memory by accessing the Task Priority Register (TPR). La función patch_instruction en hw/i386/kvmvapic.c en QEMU no inicializa la variable imm32, lo que permite a administradores locales del SO invitado obtener información sensible de la memoria de pila del anfitrión accediendo al Task Priority Register (TPR). An information-exposure flaw was found in Quick Emulator (QEMU) in Task Priority Register (TPR) optimizations for 32-bit Windows guests. The flaw could occur while accessing TPR. A privileged user inside a guest could use this issue to read portions of the host memory. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=691a02e2ce0c413236a78dee6f2651c937b09fb0 http://www.securityfocus.com/bid/86067 http://www.ubuntu.com/usn/USN-2974-1 https://access.redhat.com/errata/RHSA-2017:1856 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://bugzilla.redhat.com/show_bug.cgi?id=1313686 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
