https://notcve.org/view.php?id=CVE-2016-6888
Integer overflow in the net_tx_pkt_init function in hw/net/net_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (QEMU process crash) via the maximum fragmentation count, which triggers an unchecked multiplication and NULL pointer dereference. Desbordamiento de entero en la función net_tx_pkt_enit en hw/net/net_tx_pkt.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (caída del proceso QEMU) a través del conteo máximo de fragmentación, lo que desencadena una multiplicación no comprobada y referencia a un puntero NULL. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=47882fa4975bf0b58dd74474329fdd7154e8f04c http://www.openwall.com/lists/oss-security/2016/08/19/10 http://www.openwall.com/lists/oss-security/2016/08/19/6 http://www.securityfocus.com/bid/92556 https://access.redhat.com/errata/RHSA-2017:2392 https://access.redhat.com/errata/RHSA-2017:2408 https://lists.debian.org/debian-lts-announce/2018/11/msg00038.html https://lists.gnu.org/archive/html/qemu-devel/2016-08/msg03176.html https • CWE-190: Integer Overflow or Wraparound CWE-476: NULL Pointer Dereference •

NOTE: this can be leveraged to execute arbitrary code with root privileges by setting malloc_lib. NOTE: the affected MySQL version information is from Oracle's October 2016 CPU. Oracle has not commented on third-party claims that the issue was silently patched in MySQL 5.5.52, 5.6.33, and 5.7.15.

https://notcve.org/view.php?id=CVE-2016-5403
The virtqueue_pop function in hw/virtio/virtio.c in QEMU allows local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) by submitting requests without waiting for completion. La función virtqueue_pop en hw/virtio/virtio.c en QEMU permite a administradores locales del SO invitado provocar una denegación de servicio (consumo de memoria y caida del proceso QUEMU) mediante la presentación de solicitudes sin esperar la finalización. Quick Emulator (QEMU) built with the virtio framework is vulnerable to an unbounded memory allocation issue. It was found that a malicious guest user could submit more requests than the virtqueue size permits. Processing a request allocates a VirtQueueElement results in unbounded memory allocation on the host controlled by the guest. • http://rhn.redhat.com/errata/RHSA-2016-1585.html http://rhn.redhat.com/errata/RHSA-2016-1586.html http://rhn.redhat.com/errata/RHSA-2016-1606.html http://rhn.redhat.com/errata/RHSA-2016-1607.html http://rhn.redhat.com/errata/RHSA-2016-1652.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 • CWE-400: Uncontrolled Resource Consumption •

Cross-site scripting (XSS) vulnerability in OpenStack Dashboard (Horizon) 8.0.1 and earlier and 9.0.0 through 9.0.1 allows remote authenticated users to inject arbitrary web script or HTML by injecting an AngularJS template in a dashboard form. Vulnerabilidad de XSS en OpenStack Dashboard (Horizon) 8.0.1 y versiones anteriores y 9.0.0 hasta la versión 9.0.1 permite a usuarios remotos autenticados inyectar secuencias de comandos web o HTML arbitrario inyectando una plantilla AngularJS en un formulario del cuadro de mandos. A DOM-based, cross-site scripting vulnerability was found in the OpenStack dashboard, where user input was not filtered correctly. An authenticated dashboard user could exploit the flaw by injecting an AngularJS template into a dashboard form (for example, using an image's description), triggering the vulnerability when another user browsed the affected page. As a result, this flaw could result in user accounts being compromised (for example, user-access credentials being stolen). • http://www.debian.org/security/2016/dsa-3617 http://www.openwall.com/lists/oss-security/2016/06/17/4 https://access.redhat.com/errata/RHSA-2016:1268 https://access.redhat.com/errata/RHSA-2016:1269 https://access.redhat.com/errata/RHSA-2016:1270 https://access.redhat.com/errata/RHSA-2016:1271 https://access.redhat.com/errata/RHSA-2016:1272 https://bugs.launchpad.net/horizon/+bug/1567673 https://review.openstack.org/329996 https://review.openstack.org/329997 https&# • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

https://notcve.org/view.php?id=CVE-2016-5126
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 •
