CVE-2014-7970 – Kernel: fs: VFS denial of service
https://notcve.org/view.php?id=CVE-2014-7970
The pivot_root implementation in fs/namespace.c in the Linux kernel through 3.17 does not properly interact with certain locations of a chroot directory, which allows local users to cause a denial of service (mount-tree loop) via . (dot) values in both arguments to the pivot_root system call. La implementación pivot_root en fs/namespace.c en el kernel de Linux hasta 3.17 no interactúa debidamente con ciertas localizaciones de un directorio chroot, lo que permite a usuarios locales causar una denegación de servicio (bucle de montaje de árbol) a través de valores . (punto) en ambos argumentos en la llamada de sistema pivot_root. • http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://secunia.com/advisories/60174 http://secunia.com/advisories/61142 http://www.openwall.com/lists/oss-security/2014/10/08/21 http://www.securityfocus.com/bid/70319 http://www.securitytracker.com/id/1030991 http://www.spinics.net/lists/linux-fsdevel/msg79153.html http://www.ubuntu.com/usn/USN-2419-1 http://www.ubuntu.com/usn/USN-2420-1 http://www.ubuntu.com/usn/USN-2513-1 http: • CWE-400: Uncontrolled Resource Consumption •
CVE-2014-8086 – Kernel: fs: ext4 race condition
https://notcve.org/view.php?id=CVE-2014-8086
Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service (file unavailability) via a combination of a write action and an F_SETFL fcntl operation for the O_DIRECT flag. Condición de carrera en la función ext4_file_write_iter en fs/ext4/file.c en el kernel de Linux hasta 3.17 permite a usuarios locales causar una denegación de servicio (no disponibilidad de ficheros) a través de una combinación de una acción de escritura y una operación F_SETFL fcntl para el indicador O_DIRECT. A race condition flaw was found in the Linux kernel's ext4 file system implementation that allowed a local, unprivileged user to crash the system by simultaneously writing to a file and toggling the O_DIRECT flag using fcntl(F_SETFL) on that file. • http://lists.opensuse.org/opensuse-security-announce/2015-09/msg00004.html http://rhn.redhat.com/errata/RHSA-2015-0290.html http://rhn.redhat.com/errata/RHSA-2015-0694.html http://www.openwall.com/lists/oss-security/2014/10/09/25 http://www.securityfocus.com/bid/70376 http://www.spinics.net/lists/linux-ext4/msg45683.html http://www.spinics.net/lists/linux-ext4/msg45685.html https://bugzilla.redhat.com/show_bug.cgi?id=1151353 https://exchange.xforce.ibmcloud.com/vulnerabi • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
CVE-2012-6657 – Kernel: net: guard tcp_set_keepalive against crash
https://notcve.org/view.php?id=CVE-2012-6657
The sock_setsockopt function in net/core/sock.c in the Linux kernel before 3.5.7 does not ensure that a keepalive action is associated with a stream socket, which allows local users to cause a denial of service (system crash) by leveraging the ability to create a raw socket. La función sock_setsockopt en net/core/sock.c en el kernel de Linux anterior a 3.5.7 no asegura que una acción keepalive está asociada con un socket de flujo, lo que permite a usuarios locales causar una denegación de servicio (caída del sistema) mediante el aprovechamiento de la habilidad de crear un socket en bruto. It was found that the Linux kernel's networking implementation did not correctly handle the setting of the keepalive socket option on raw sockets. A local user able to create a raw socket could use this flaw to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=3e10986d1d698140747fcfc2761ec9cb64c1d582 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://marc.info/?l=bugtraq&m=142722450701342&w=2 http://marc.info/?l=bugtraq&m=142722544401658&w=2 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.5.7 http://www.openwall.com/lists/oss-security/2014/09 • CWE-264: Permissions, Privileges, and Access Controls •

net/ceph/auth_x.c in Ceph, as used in the Linux kernel before 3.16.3, does not properly validate auth replies, which allows remote attackers to cause a denial of service (system crash) or possibly have unspecified other impact via crafted data from the IP address of a Ceph Monitor. net/ceph/auth_x.c en Ceph, utilizado en el kernel de Linux anterior a 3.16.3, no valida debidamente las respuestas de autor válidas, lo que permite a atacantes remotos causar una denegación de servicio (caída del sistema) o posiblemente tener otro impacto no especificado a través de datos manipulados de la dirección IP de un monitor Ceph. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c27a3e4d667fdcad3db7b104f75659478e0c68d8 http://tracker.ceph.com/issues/8979 http://tracker.ceph.com/issues/9561 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.3 http://www.openwall.com/lists/oss-security/2014/09/15/7 http://www.ubuntu.com/usn/USN-2376-1 http://www.ubuntu.com/usn/USN-2377-1 http://www.ubuntu.com/usn/USN-2378-1 http://www.ubuntu.com/usn/USN • CWE-399: Resource Management Errors •
CVE-2014-3181 – Kernel: HID: OOB write in magicmouse driver
https://notcve.org/view.php?id=CVE-2014-3181
Multiple stack-based buffer overflows in the magicmouse_raw_event function in drivers/hid/hid-magicmouse.c in the Magic Mouse HID driver in the Linux kernel through 3.16.3 allow physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that provides a large amount of (1) EHCI or (2) XHCI data associated with an event. Múltiples desbordamientos de buffer basado en pila en la función magicmouse_raw_event en drivers/hid/hid-magicmouse.c en el controlador Magic Mouse HID en el kernel de Linux hasta 3.16.3 permiten a atacantes físicamente próximos causar una denegación de servicio (caída del sistema) o posiblemente ejecutar código arbitrario a través de un dispositivo que proporciona una cantidad grande de datos (1) EHCI o (2) XHCI asociados con un evento. An out-of-bounds write flaw was found in the way the Apple Magic Mouse/Trackpad multi-touch driver handled Human Interface Device (HID) reports with an invalid size. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c54def7bd64d7c0b6993336abcffb8444795bf38 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://rhn.redhat.com/errata/RHSA-2014-1318.html http://www.openwall.com/lists/oss-security/2014/09/11/21 http://www.securityfocus.com/bid/69779 http://www.ubuntu.com/usn/USN-2376-1 http://www.ubuntu.com/usn/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
