https://notcve.org/view.php?id=CVE-2016-8910
The rtl8139_cplus_transmit function in hw/net/rtl8139.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) by leveraging failure to limit the ring descriptor count. La función rtl8139_cplus_transmit en hw/net/rtl8139.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (bucle infinito y consumo de CPU) aprovechando el fallo para limitar el recuento del descriptor del anillo. • http://lists.opensuse.org/opensuse-updates/2016-12/msg00140.html http://www.openwall.com/lists/oss-security/2016/10/24/2 http://www.openwall.com/lists/oss-security/2016/10/24/5 http://www.securityfocus.com/bid/93844 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/2016-10/msg05495.html https://security. • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

The serial_update_parameters function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (divide-by-zero error and QEMU process crash) via vectors involving a value of divider greater than baud base. La función serial_update_parameters en hw/char/serial.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (error de división por cero y caída del proceso QEMU) a través de vectores que involucran un valor de divisor mayor que la base baud. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=3592fe0c919cf27a81d8e9f9b4f269553418bb01 http://lists.opensuse.org/opensuse-updates/2016-12/msg00140.html http://www.openwall.com/lists/oss-security/2016/10/14/9 http://www.openwall.com/lists/oss-security/2016/10/15/5 http://www.securityfocus.com/bid/93563 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:/&#x • CWE-369: Divide By Zero •

The virtqueue_map_desc function in hw/virtio/virtio.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via a large I/O descriptor buffer length value. La función virtqueue_map_desc en hw/virtio/virtio.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (referencia a puntero NULL y caída del proceso QEMU) a través de un gran valor de longitud de búfer descriptor de I/O. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=973e7170dddefb491a48df5cba33b2ae151013a0 http://lists.opensuse.org/opensuse-updates/2016-12/msg00140.html http://www.openwall.com/lists/oss-security/2016/09/16/10 http://www.openwall.com/lists/oss-security/2016/09/16/4 http://www.securityfocus.com/bid/92996 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/msg03546.html https:&# • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-476: NULL Pointer Dereference •

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 •

Oracle MySQL through 5.5.52, 5.6.x through 5.6.33, and 5.7.x through 5.7.15; MariaDB before 5.5.51, 10.0.x before 10.0.27, and 10.1.x before 10.1.17; and Percona Server before 5.5.51-38.1, 5.6.x before 5.6.32-78.0, and 5.7.x before 5.7.14-7 allow local users to create arbitrary configurations and bypass certain protection mechanisms by setting general_log_file to a my.cnf configuration. 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.
