CVE-2016-9084 – kernel: Integer overflow when using kzalloc in vfio driver
https://notcve.org/view.php?id=CVE-2016-9084
drivers/vfio/pci/vfio_pci_intrs.c in the Linux kernel through 4.8.11 misuses the kzalloc function, which allows local users to cause a denial of service (integer overflow) or have unspecified other impact by leveraging access to a vfio PCI device file. drivers/vfio/pci/vfio_pci_intrs.c en el kernel Linux hasta la versión 4.8.11 usa de forma incorrecta la función kzalloc, lo que permite a usuarios locales provocar una denegación de servicio (desbordamiento de entero) o tener otro posible impacto no especificado aprovechando el acceso al archivo de dispositivo vfio PCI. The use of a kzalloc with an integer multiplication allowed an integer overflow condition to be reached in vfio_pci_intrs.c. This combined with CVE-2016-9083 may allow an attacker to craft an attack and use unallocated memory, potentially crashing the machine. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=05692d7005a364add85c6e25a6c4447ce08f913a http://rhn.redhat.com/errata/RHSA-2017-0386.html http://rhn.redhat.com/errata/RHSA-2017-0387.html http://www.openwall.com/lists/oss-security/2016/10/26/11 http://www.securityfocus.com/bid/93930 https://bugzilla.redhat.com/show_bug.cgi?id=1389259 https://github.com/torvalds/linux/commit/05692d7005a364add85c6e25a6c4447ce08f913a https://patchwork.kernel.org/patch/9373631 https:/ • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2016-9191
The cgroup offline implementation in the Linux kernel through 4.8.11 mishandles certain drain operations, which allows local users to cause a denial of service (system hang) by leveraging access to a container environment for executing a crafted application, as demonstrated by trinity. La implementación offline cgroup en el kernel Linux hasta la versión 4.8.11 maneja incorrectamente ciertas operaciones drain, lo que permite a usuarios locales provocar una denegación de servicio (colgado de sistema) aprovechando el acceso al contenedor de ambiente para ejecutar una aplicación manipulada, como es demostrado por trinity. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=93362fa47fe98b62e4a34ab408c4a418432e7939 http://www.debian.org/security/2017/dsa-3791 http://www.openwall.com/lists/oss-security/2016/11/05/4 http://www.securityfocus.com/bid/94129 https://bugzilla.redhat.com/show_bug.cgi?id=1392439 https://github.com/torvalds/linux/commit/93362fa47fe98b62e4a34ab408c4a418432e7939 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03802en_us • CWE-20: Improper Input Validation CWE-399: Resource Management Errors •

The tipc_msg_build function in net/tipc/msg.c in the Linux kernel through 4.8.11 does not validate the relationship between the minimum fragment length and the maximum packet size, which allows local users to gain privileges or cause a denial of service (heap-based buffer overflow) by leveraging the CAP_NET_ADMIN capability. La función tipc_msg_build en net/tipc/msg.c en el kernel Linux hasta la versión 4.8.11 no valida la relación entre la longitud mínima de fragmento y el tamaño máximo de paquete, lo que permite a usuarios locales obtener privilegios o provocar una denegación de servicio (desbordamiento de búfer basado en memoria dinámica) aprovechando la capacidad CAP_NET_ADMIN. • http://www.openwall.com/lists/oss-security/2016/11/08/5 http://www.securityfocus.com/bid/94211 https://bugzilla.redhat.com/show_bug.cgi?id=1390832 https://www.mail-archive.com/netdev%40vger.kernel.org/msg133205.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-264: Permissions, Privileges, and Access Controls •
CVE-2016-9555 – kernel: Slab out-of-bounds access in sctp_sf_ootb()
https://notcve.org/view.php?id=CVE-2016-9555
The sctp_sf_ootb function in net/sctp/sm_statefuns.c in the Linux kernel before 4.8.8 lacks chunk-length checking for the first chunk, which allows remote attackers to cause a denial of service (out-of-bounds slab access) or possibly have unspecified other impact via crafted SCTP data. La función sctp_sf_ootb en net/sctp/sm_statefuns.c en el kernel Linux en versiones anteriores a 4.8.8 carece de comprobación de longitud de fragmento para el primer fragmento, lo que permite a atacantes remotos provocar una denegación de servicio (acceso slab fuera de límites) o tener otro posible impacto no especificado a través de datos SCTP manipulados. A flaw was found in the Linux kernel's implementation of the SCTP protocol. A remote attacker could trigger an out-of-bounds read with an offset of up to 64kB potentially causing the system to crash. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bf911e985d6bbaa328c20c3e05f4eb03de11fdd6 http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00055.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016-12/msg00067.html http://lists.opensuse.org • CWE-125: Out-of-bounds Read •
CVE-2016-8633 – kernel: Buffer overflow in firewire driver via crafted incoming packets
https://notcve.org/view.php?id=CVE-2016-8633
drivers/firewire/net.c in the Linux kernel before 4.8.7, in certain unusual hardware configurations, allows remote attackers to execute arbitrary code via crafted fragmented packets. drivers/firewire/net.c en el kernel Linux en versiones anteriores a 4.8.7, en ciertas configuraciones de hardware no usuales, permite a atacantes remotos ejecutar un código arbitrario a través de paquetes fragmentados manipulados. A buffer overflow vulnerability due to a lack of input filtering of incoming fragmented datagrams was found in the IP-over-1394 driver [firewire-net] in a fragment handling code in the Linux kernel. The vulnerability exists since firewire supported IPv4, i.e. since version 2.6.31 (year 2009) till version v4.9-rc4. A maliciously formed fragment with a respectively large datagram offset would cause a memcpy() past the datagram buffer, which would cause a system panic or possible arbitrary code execution. The flaw requires [firewire-net] module to be loaded and is remotely exploitable from connected firewire devices, but not over a local network. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=667121ace9dbafb368618dbabcf07901c962ddac http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.8.7 http://www.openwall.com/lists/oss-security/2016/11/06/1 http://www.securityfocus.com/bid/94149 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1170 https://access.redhat.com/errata/RHSA-2019:1190 https:// • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-284: Improper Access Control CWE-787: Out-of-bounds Write •
