CVSS: 5.5EPSS: 0%CPEs: 5EXPL: 0CVE-2014-7975 – Kernel: fs: umount denial of service
https://notcve.org/view.php?id=CVE-2014-7975
The do_umount function in fs/namespace.c in the Linux kernel through 3.17 does not require the CAP_SYS_ADMIN capability for do_remount_sb calls that change the root filesystem to read-only, which allows local users to cause a denial of service (loss of writability) by making certain unshare system calls, clearing the / MNT_LOCKED flag, and making an MNT_FORCE umount system call. La función do_umount en fs/namespace.c en el kernel de Linux hasta 3.17 no requiere la capacidad CAP_SYS_ADMIN para llamadas do_remount_sb que cambian el sistema de ficheros root a sólo lectura, lo que permite a usuarios locales causar una denegación de servicio (pérdida de la habilidad de escritura) mediante la realización de ciertas llamadas a la liberación de sistemas, la limpieza del indicador / MNT_LOCKED, y la realización de una llamada al sistema umount MNT_FORCE. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0ef3a56b1c466629cd0bf482b09c7b0e5a085bb5 http://secunia.com/advisories/60174 http://secunia.com/advisories/61145 http://secunia.com/advisories/62633 http://secunia.com/advisories/62634 http://thread.gmane.org/gmane.linux.kernel.stable/109312 http://www.openwall.com/lists/oss-security/2014/10/08/22 http://www.securityfocus.com/bid/70314 http://www.securitytracker.com/id/1031180 http://www.ubuntu.com/usn/US •

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 •

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&#x • 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 •

Buffer overflow in the picolcd_raw_event function in devices/hid/hid-picolcd_core.c in the PicoLCD HID device driver in the Linux kernel through 3.16.3, as used in Android on Nexus 7 devices, allows physically proximate attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a crafted device that sends a large report. Desbordamiento de buffer en la función picolcd_raw_event en devices/hid/hid-picolcd_core.c en el controlador de dispositivos PicoLCD HID en el kernel de Linux hasta 3.16.3, utilizado en Android en los dispositivos Nexus 7, permite a atacantes físicamente próximos causar una denegación de servicio (caída del sistema) o posiblemente ejecutar código arbitrario a través de un dispositivo manipulado que envía un informe grande. A buffer overflow flaw was found in the way the Minibox PicoLCD 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=844817e47eef14141cf59b8d5ac08dd11c0a9189 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://www.openwall.com/lists/oss-security/2014/09/11/22 http://www.securityfocus.com/bid/69763 http://www.ubuntu.com/usn/USN-2376-1 http://www.ubuntu.com/usn/USN-2377-1 http://www.ubuntu.com/usn/USN-2378- • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
