https://notcve.org/view.php?id=CVE-2016-6835
The vmxnet_tx_pkt_parse_headers function in hw/net/vmxnet_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (buffer over-read) by leveraging failure to check IP header length. La función vmxnet_tx_pkt_parse_headers en hw/net/vmxnet_tx_pkt.c en QEMU (también conocido como Quick Emulator) permite a administradores locales del SO invitado provocar una denegación de servicio (sobre lectura del búfer) aprovechando el fallo para comprobar la longitud del encabezado IP. • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=93060258ae748573ca7197204125a2670047896d http://www.openwall.com/lists/oss-security/2016/08/11/7 http://www.openwall.com/lists/oss-security/2016/08/18/4 https://access.redhat.com/errata/RHSA-2017:2392 https://lists.debian.org/debian-lts-announce/2018/09/msg00007.html https://lists.gnu.org/archive/html/qemu-stable/2016-08/msg00077.html https://access.redhat.com/security/cve/CVE-2016-6835 https://bugzilla.redhat.com/show_bug • CWE-122: Heap-based Buffer Overflow •

https://notcve.org/view.php?id=CVE-2015-8817
QEMU (aka Quick Emulator) built to use 'address_space_translate' to map an address to a MemoryRegionSection is vulnerable to an OOB r/w access issue. It could occur while doing pci_dma_read/write calls. Affects QEMU versions >= 1.6.0 and <= 2.3.1. A privileged user inside guest could use this flaw to crash the guest instance resulting in DoS.

The cpu_physical_memory_write_rom_internal function in exec.c in QEMU (aka Quick Emulator) does not properly skip MMIO regions, which allows local privileged guest users to cause a denial of service (guest crash) via unspecified vectors. La función cpu_physical_memory_write_rom_internal en exec.c en QEMU (también conocido como Quick Emulator) no omite apropiadamente las regiones MMIO, lo que permite a usuarios invitados privilegiados locales provocar una denegación de servicio (caída del huésped) a través de vectores no especificados. An out-of-bounds flaw was found in the QEMU emulator built using 'address_space_translate' to map an address to a MemoryRegionSection. The flaw could occur while doing pci_dma_read/write calls, resulting in an out-of-bounds read-write access error. A privileged user inside a guest could use this flaw to crash the guest instance (denial of service). • http://git.qemu.org/?p=qemu.git%3Ba=commit%3Bh=b242e0e0e2969c044a318e56f7988bbd84de1f63 http://rhn.redhat.com/errata/RHSA-2016-2670.html http://rhn.redhat.com/errata/RHSA-2016-2671.html http://rhn.redhat.com/errata/RHSA-2016-2704.html http://rhn.redhat.com/errata/RHSA-2016-2705.html http://rhn.redhat.com/errata/RHSA-2016-2706.html http://www.openwall.com/lists/oss-security/2016/03/01/1 http://www.openwall.com/lists/oss-security/2016/03/01/10 https://bugzilla. • CWE-787: Out-of-bounds Write •
