The (1) esp_reg_read and (2) esp_reg_write functions in hw/scsi/esp.c in QEMU allow local guest OS administrators to cause a denial of service (QEMU process crash) or execute arbitrary code on the QEMU host via vectors related to the information transfer buffer. Las funciones (1) esp_reg_read y (2) esp_reg_write en hw/scsi/esp.c en QEMU permite a administradores locales del SO invitado provocar una denegación de servicio (caída del proceso QEMU) o ejecutar código arbitrario en el anfitrión QEMU a través de vectores relacionados con el buffer de transferencia de información. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=ff589551c8e8e9e95e211b9d8daafb4ed39f1aec http://www.openwall.com/lists/oss-security/2016/06/07/3 http://www.openwall.com/lists/oss-security/2016/06/08/14 http://www.securityfocus.com/bid/91079 http://www.ubuntu.com/usn/USN-3047-1 http://www.ubuntu.com/usn/USN-3047-2 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg01507.html https://secur •

The get_cmd function in hw/scsi/esp.c in QEMU might allow local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via vectors related to reading from the information transfer buffer in non-DMA mode. La función get_cmd en hw/scsi/esp.c en QEMU podría permitir a administradores locales del SO invitado provocar una denegación de servicio (escritura fuera de límites y caída del proceso QEMU) a través de vectores relacionados con la lectura del buffer de transferencia de información en modo no DMA. • http://www.openwall.com/lists/oss-security/2016/06/02/2 http://www.openwall.com/lists/oss-security/2016/06/02/9 http://www.securityfocus.com/bid/90995 http://www.ubuntu.com/usn/USN-3047-1 http://www.ubuntu.com/usn/USN-3047-2 https://bugzilla.redhat.com/show_bug.cgi?id=1341931 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg05691.html https://lists.gnu.org/archive/html/qemu • CWE-787: Out-of-bounds Write •

The megasas_ctrl_get_info function in hw/scsi/megasas.c in QEMU allows local guest OS administrators to obtain sensitive host memory information via vectors related to reading device control information. La función megasas_ctrl_get_info en hw/scsi/megasas.c en QEMU permite a administradores locales del SO invitado obtener información sensible de la memoria del anfitrión a través de vectores relacionados con la lectura de información de control del dispositivo. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=844864fbae66935951529408831c2f22367a57b6 http://www.openwall.com/lists/oss-security/2016/06/08/13 http://www.openwall.com/lists/oss-security/2016/06/08/3 http://www.securityfocus.com/bid/91097 http://www.ubuntu.com/usn/USN-3047-1 http://www.ubuntu.com/usn/USN-3047-2 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-06/msg01969.html https://secur •

The vmsvga_fifo_read_raw function in hw/display/vmware_vga.c in QEMU allows local guest OS administrators to obtain sensitive host memory information or cause a denial of service (QEMU process crash) by changing FIFO registers and issuing a VGA command, which triggers an out-of-bounds read. La función vmsvga_fifo_read_raw en hw/display/vmware_vga.c en QEMU permite a administradores locales del SO invitado obtener información sensible de la memoria del anfitrión o provocar una denegación de servicio (caída del proceso QEMU) cambiando registros FIFO y emitiendo un comando VGA, lo que desencadena una lectura fuera de rango. • http://www.openwall.com/lists/oss-security/2016/05/30/3 http://www.securityfocus.com/bid/90927 http://www.ubuntu.com/usn/USN-3047-1 http://www.ubuntu.com/usn/USN-3047-2 https://bugzilla.redhat.com/show_bug.cgi?id=1336429 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg05271.html https://security.gentoo.org/glsa/201609-01 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

Heap-based buffer overflow in the iscsi_aio_ioctl function in block/iscsi.c in QEMU allows local guest OS users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code via a crafted iSCSI asynchronous I/O ioctl call. Desbordamiento de buffer basado en memoria dinámica en la función iscsi_aio_ioctl en block/iscsi.c en QEMU permite a usuarios locales del SO invitado provocar una denegación de servicio (caída del proceso QEMU) o posiblemente ejecutar código arbitrario a través de una llamada iSCSI ioctl I/O asíncrona manipulada. Quick Emulator(QEMU) built with the Block driver for iSCSI images support (virtio-blk) is vulnerable to a heap-based buffer overflow issue. The flaw could occur while processing iSCSI asynchronous I/O ioctl(2) calls. A user inside a guest could exploit this flaw to crash the QEMU process resulting in denial of service, or potentially leverage it to execute arbitrary code with QEMU-process privileges on the host. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=a6b3167fa0e825aebb5a7cd8b437b6d41584a196 http://rhn.redhat.com/errata/RHSA-2016-1606.html http://rhn.redhat.com/errata/RHSA-2016-1607.html http://rhn.redhat.com/errata/RHSA-2016-1653.html http://rhn.redhat.com/errata/RHSA-2016-1654.html http://rhn.redhat.com/errata/RHSA-2016-1655.html http://rhn.redhat.com/errata/RHSA-2016-1756.html http://rhn.redhat.com/errata/RHSA-2016-1763.html http://www.openwall.com/lists/oss-secu • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
