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 •

https://notcve.org/view.php?id=CVE-2016-8650
The mpi_powm function in lib/mpi/mpi-pow.c in the Linux kernel through 4.8.11 does not ensure that memory is allocated for limb data, which allows local users to cause a denial of service (stack memory corruption and panic) via an add_key system call for an RSA key with a zero exponent. La función mpi_powm en lib/mpi/mpi-pow.c en el kernel Linux hasta la versión 4.8.11 no se asegura que la memoria esté alojada para datos limb, lo que permite a usuarios locales provocar una denegación de servicio (corrupción de memoria de pila y pánico) a través de una llamada de sistema add_key para una llave RSA con un componente cero. A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory (denial of service) by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f5527fffff3f002b0a6b376163613b82f69de073 http://seclists.org/fulldisclosure/2016/Nov/76 http://www.openwall.com/lists/oss-security/2016/11/24/8 http://www.securityfocus.com/bid/94532 http://www.securitytracker.com/id/1037968 https://access.redhat.com/errata/RHSA-2017:0931 https://access.redhat.com/errata/RHSA-2017:0932 https://access.redhat.com/errata/RHSA-2017:0933 https://access.redhat.com/errata/RHSA- • CWE-20: Improper Input Validation CWE-399: Resource Management Errors CWE-476: NULL Pointer Dereference •

The __get_user_asm_ex macro in arch/x86/include/asm/uaccess.h in the Linux kernel before 4.7.5 does not initialize a certain integer variable, which allows local users to obtain sensitive information from kernel stack memory by triggering failure of a get_user_ex call. El macro __get_user_asm_ex en arch/x86/include/asm/uaccess.h en el kernel Linux en versiones anteriores a 4.7.5 no inicia ciertas variables de entero, lo que permite a usuarios locales obtener información sensible de la memoria basado en pila del kernel desencadenando un fallo de la llamada get_user_ex. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=1c109fabbd51863475cd12ac206bdd249aee35af http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.7.5 http://www.openwall.com/lists/oss-security/2016/11/04/4 http://www.securityfocus.com/bid/94144 https://bugzilla.redhat.com/show_bug.cgi?id=1391908 https://github.com/torvalds/linux/commit/1c109fabbd51863475cd12ac206bdd249aee35af • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

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 •

https://notcve.org/view.php?id=CVE-2016-7910
Use-after-free vulnerability in the disk_seqf_stop function in block/genhd.c in the Linux kernel before 4.7.1 allows local users to gain privileges by leveraging the execution of a certain stop operation even if the corresponding start operation had failed. Vulnerabilidad de uso después de liberación de memoria en la función disk_seqf_stop en block/genhd.c en el kernel de Linux en versiones anteriores a 4.7.1 permite a usuarios locales obtener privilegios aprovechando la ejecución de una cierta operación de parada incluso si la operación de arranque correspondiente hubiera fallado. A flaw was found in the Linux kernel's implementation of seq_file where a local attacker could manipulate memory in the put() function pointer. This could lead to memory corruption and possible privileged escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=77da160530dd1dc94f6ae15a981f24e5f0021e84 http://source.android.com/security/bulletin/2016-11-01.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.7.1 http://www.securityfocus.com/bid/94135 https://access.redhat.com/errata/RHSA-2017:0892 https://access.redhat.com/errata/RHSA-2017:1297 https://access.redhat.com/errata/RHSA-2017:1298 https://access.redhat.com/errata/RHSA-2017:1308 https://gi • CWE-416: Use After Free •
