https://notcve.org/view.php?id=CVE-2016-8909
The intel_hda_xfer function in hw/audio/intel-hda.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and CPU consumption) via an entry with the same value for buffer length and pointer position. La función intel_hda_xfer en hw/audio/intel-hda.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) a través de una entrada con el mismo valor para la longitud del búfer y posición del puntero. • http://lists.opensuse.org/opensuse-updates/2016-12/msg00140.html http://www.openwall.com/lists/oss-security/2016/10/24/1 http://www.openwall.com/lists/oss-security/2016/10/24/4 http://www.securityfocus.com/bid/93842 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/msg04682.html https://security. • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

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') •

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 •
