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 •

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 •

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 •

A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory. Se ha encontrado un fallo en el manejo del kernel de Linux para borrar los atributos SELinux de los ficheros /proc/pid/attr en versiones anteriores a la 4.9.10. Una escritura vacía (null) en este archivo puede cerrar de manera inesperada el sistema haciendo que el sistema intente acceder a la memoria no mapeada del kernel.
