Multiple heap-based buffer overflows in the hiddev_ioctl_usage function in drivers/hid/usbhid/hiddev.c in the Linux kernel through 4.6.3 allow local users to cause a denial of service or possibly have unspecified other impact via a crafted (1) HIDIOCGUSAGES or (2) HIDIOCSUSAGES ioctl call. Múltiples desbordamientos de buffer basado en memoria dinámica en la función hiddev_ioctl_usage en drivers/hid/usbhid/hiddev.c en el kernel de Linux hasta la versión 4.6.3 permiten a usuarios locales provocar una denegación de servicio o tener posiblemente otro impacto no especificado a través de una llamada (1) HIDIOCGUSAGES o (2) HIDIOCSUSAGES ioctl manipulada. A heap-based buffer overflow vulnerability was found in the Linux kernel's hiddev driver. This flaw could allow a local attacker to corrupt kernel memory, possible privilege escalation or crashing the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=93a2001bdfd5376c3dc2158653034c20392d15c5 http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00048.html http://lists.opensuse.org • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-122: Heap-based Buffer Overflow •

Race condition in the vop_ioctl function in drivers/misc/mic/vop/vop_vringh.c in the MIC VOP driver in the Linux kernel before 4.6.1 allows local users to obtain sensitive information from kernel memory or cause a denial of service (memory corruption and system crash) by changing a certain header, aka a "double fetch" vulnerability. Condición de carrera en la función vop_ioctl en drivers/misc/mic/vop/vop_vringh.c en el controlador MIC VOP en el kernel de Linux en versiones anteriores a 4.6.1 permite a usuarios locales obtener información sensible desde la memoria del kernel o causar una denegación de servicio (corrupción de memoria y caída del sistema) cambiando cierta cabecera, también conocida como vulnerabilidad "double fetch". • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=9bf292bfca94694a721449e3fd752493856710f6 http://www.debian.org/security/2016/dsa-3616 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.6.1 http://www.securityfocus.com/archive/1/538802/30/0/threaded http://www.ubuntu.com/usn/USN-3070-1 http://www.ubuntu.com/usn/USN-3070-2 http://www.ubuntu.com/usn/USN-3070-3 http://www.ubuntu.com/usn/USN-3070-4 http://www.ubuntu.com/u • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The tipc_nl_compat_link_dump function in net/tipc/netlink_compat.c in the Linux kernel through 4.6.3 does not properly copy a certain string, which allows local users to obtain sensitive information from kernel stack memory by reading a Netlink message. La función tipc_nl_compat_link_dump en net/tipc/netlink_compat.c en el kernel de Linux hasta la versión 4.6.3 no copia adecuadamente una cierta cadena, lo que permite a usuarios locales obtener información sensible de la memoria de pila del kernel leyendo un mensaje Netlink. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=5d2be1422e02ccd697ccfcd45c85b4a26e6178e2 http://www.debian.org/security/2016/dsa-3607 http://www.openwall.com/lists/oss-security/2016/06/03/4 http://www.securityfocus.com/bid/91334 http://www.ubuntu.com/usn/USN-3049-1 http://www.ubuntu.com/usn/USN-3050-1 http://www.ubuntu.com/usn/USN-3051-1 http://www.ubuntu.com/usn/USN-3052-1 http://www.ubuntu.com/usn/USN-3053-1 http:// • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command. La función key_reject_and_link en security/keys/key.c en el kernel de Linux hasta la versión 4.6.3 no asegura que cierta estructura de datos esté inicializada, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de vectores involucrando un comando keyctl request2 manipulado. A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=38327424b40bcebe2de92d07312c89360ac9229a http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00009.html http://lists.opensuse.org • CWE-253: Incorrect Check of Function Return Value •

The ecryptfs_privileged_open function in fs/ecryptfs/kthread.c in the Linux kernel before 4.6.3 allows local users to gain privileges or cause a denial of service (stack memory consumption) via vectors involving crafted mmap calls for /proc pathnames, leading to recursive pagefault handling. La función ecryptfs_privileged_open en fs/ecryptfs/kthread.c en el kernel de Linux en versiones anteriores a 4.6.3 permite a usuarios locales obtener privilegios o provocar una denegación de servicio (consumo de memoria de pila) a través de vectores involucrados con llamadas mmap manipuladas para nombres de ruta /proc, que conduce a una página de error recursiva manipulada. It was found that stacking a file system over procfs in the Linux kernel could lead to a kernel stack overflow due to deep nesting, as demonstrated by mounting ecryptfs over procfs and creating a recursion by mapping /proc/environ. An unprivileged, local user could potentially use this flaw to escalate their privileges on the system. There is a stack overflow in Linux via ecryptfs and /proc/$pid/environ. • https://www.exploit-db.com/exploits/39992 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2f36db71009304b3f0b95afacd8eba1f9f046b87 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f5364c150aa645b3d7daa21b5c0b9feaa1c9cd6d http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opens • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-121: Stack-based Buffer Overflow •
