https://notcve.org/view.php?id=CVE-2017-6345
The LLC subsystem in the Linux kernel before 4.9.13 does not ensure that a certain destructor exists in required circumstances, which allows local users to cause a denial of service (BUG_ON) or possibly have unspecified other impact via crafted system calls. El subsistema LLC en el kernel de Linux en versiones anteriores a 4.9.13 no garantiza que exista cierto destructor en las circunstancias requeridas, lo que permite a usuarios locales provocar una denegación de servicio (BUG_ON) o posiblemente tener otro impacto no especificado a través de llamadas al sistema manipuladas. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=8b74d439e1697110c5e5c600643e823eb1dd0762 http://www.debian.org/security/2017/dsa-3804 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.13 http://www.openwall.com/lists/oss-security/2017/02/28/7 http://www.securityfocus.com/bid/96510 https://github.com/torvalds/linux/commit/8b74d439e1697110c5e5c600643e823eb1dd0762 https://usn.ubuntu.com/3754-1 • CWE-20: Improper Input Validation •
CVE-2017-6348
https://notcve.org/view.php?id=CVE-2017-6348
The hashbin_delete function in net/irda/irqueue.c in the Linux kernel before 4.9.13 improperly manages lock dropping, which allows local users to cause a denial of service (deadlock) via crafted operations on IrDA devices. La función hashben_delete en net/irda/irqueue.c en el kernel de Linux en versiones anteriores a 4.9.13 administra incorrectamente el soltado del bloqueo, lo que permite a usuarios locales provocar una denegación de servicio (punto muerto) a través de operaciones manipuladas en los dispositivos IrDA. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=4c03b862b12f980456f9de92db6d508a4999b788 http://www.debian.org/security/2017/dsa-3804 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.13 http://www.openwall.com/lists/oss-security/2017/02/28/4 http://www.securityfocus.com/bid/96483 https://github.com/torvalds/linux/commit/4c03b862b12f980456f9de92db6d508a4999b788 https://usn.ubuntu.com/3754-1 •
CVE-2017-6346
https://notcve.org/view.php?id=CVE-2017-6346
Race condition in net/packet/af_packet.c in the Linux kernel before 4.9.13 allows local users to cause a denial of service (use-after-free) or possibly have unspecified other impact via a multithreaded application that makes PACKET_FANOUT setsockopt system calls. Condición de carrera en net/packet/af_packet.c en el kernel de Linux en versiones anteriores a 4.9.13 permite a usuarios locales provocar una denegación de servicio (uso después de liberación de memoria) o la posibilidad de tener otro impacto no especificado a través de una aplicación multihilo que realizada llamadas al sistema PACKET_FANOUT setsockopt. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d199fab63c11998a602205f7ee7ff7c05c97164b http://www.debian.org/security/2017/dsa-3804 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.13 http://www.openwall.com/lists/oss-security/2017/02/28/6 http://www.securityfocus.com/bid/96508 https://github.com/torvalds/linux/commit/d199fab63c11998a602205f7ee7ff7c05c97164b https://source.android.com/security/bulletin/2017-09-01 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVE-2017-5669
https://notcve.org/view.php?id=CVE-2017-5669
The do_shmat function in ipc/shm.c in the Linux kernel through 4.9.12 does not restrict the address calculated by a certain rounding operation, which allows local users to map page zero, and consequently bypass a protection mechanism that exists for the mmap system call, by making crafted shmget and shmat system calls in a privileged context. La función do_shmat en ipc/shm.c en el kernel de Linux hasta la versión 4.9.12 no restringe la dirección calculada por cierta operación de redondeo, lo que permite a usuarios locales asignar la página cero, y como consecuencia, eludir un mecanismo de protección que existe por la llamada de sistema mmap, haciendo llamadas a sistema shmget y shmat manipuladas en un contexto privilegiado. • http://www.debian.org/security/2017/dsa-3804 http://www.securityfocus.com/bid/96754 http://www.securitytracker.com/id/1037918 https://bugzilla.kernel.org/show_bug.cgi?id=192931 https://github.com/torvalds/linux/commit/95e91b831f87ac8e1f8ed50c14d709089b4e01b8 https://github.com/torvalds/linux/commit/e1d35d4dc7f089e6c9c080d556feedf9c706f0c7 https://usn.ubuntu.com/3583-1 https://usn.ubuntu.com/3583-2 •
CVE-2017-5897
https://notcve.org/view.php?id=CVE-2017-5897
The ip6gre_err function in net/ipv6/ip6_gre.c in the Linux kernel allows remote attackers to have unspecified impact via vectors involving GRE flags in an IPv6 packet, which trigger an out-of-bounds access. La función ip6gre_err en net/ipv6/ip6_gre.c en el kernel de Linux permite a atacantes remotos tener impacto no especificado a través de vectores involucrando indicadores GRE flags en un paquete IPv6, que desencadenan un acceso fuera de los límites. • http://www.debian.org/security/2017/dsa-3791 http://www.openwall.com/lists/oss-security/2017/02/07/2 http://www.securityfocus.com/bid/96037 http://www.securitytracker.com/id/1037794 https://git.kernel.org/pub/scm/linux/kernel/git/davem/net.git/commit/?id=7892032cfe67f4bde6fc2ee967e45a8fbaf33756 https://source.android.com/security/bulletin/2017-09-01 https://usn.ubuntu.com/3754-1 • CWE-125: Out-of-bounds Read •
