The capabilities implementation in the Linux kernel before 3.14.8 does not properly consider that namespaces are inapplicable to inodes, which allows local users to bypass intended chmod restrictions by first creating a user namespace, as demonstrated by setting the setgid bit on a file with group ownership of root. La implementación de capacidades en el kernel de Linux anterior a 3.14.8 no considera debidamente que los espacios de nombres no sean aplicables a inodos, lo que permite a usuarios locales evadir restricciones chmod mediante la creación anterior de un espacio de nombre de usuario, tal y como fue demostrado mediante la configuración del bit setgid en un fichero con propiedad de grupo del root. • https://www.exploit-db.com/exploits/33824 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=23adbe12ef7d3d4195e80800ab36b37bee28cd03 http://secunia.com/advisories/59220 http://www.exploit-db.com/exploits/33824 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.14.8 http://www.openwall.com/lists/oss-security/2014/06/10/4 http://www.securityfocus.com/bid/67988 http://www.securitytracker.com/id/1030394 https://bugzilla.redhat.com/show_ • CWE-264: Permissions, Privileges, and Access Controls •

The __do_follow_link function in fs/namei.c in the Linux kernel before 2.6.33 does not properly handle the last pathname component during use of certain filesystems, which allows local users to cause a denial of service (incorrect free operations and system crash) via an open system call. La función __do_follow_link en fs/namei.c en el kernel de Linux anterior a 2.6.33 no maneja debidamente el componente de último nombre de ruta durante el uso de ciertos sistemas de ficheros, lo que permite a usuarios locales causar una denegación de servicio (operaciones libres incorrectas y caída del sistema) a través de una llamada de sistema abierto. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=86acdca1b63e6890540fa19495cfc708beff3d8b http://linux.oracle.com/errata/ELSA-2014-0771.html http://linux.oracle.com/errata/ELSA-2014-3043.html http://mirror.linux.org.au/linux/kernel/v2.6/ChangeLog-2.6.33 http://secunia.com/advisories/59262 http://secunia.com/advisories/59309 http://secunia.com/advisories/59406 http://secunia.com/advisories/59560 http://www.securityfocus.com/bid/68125 https:/&#x • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2014-3153
The futex_requeue function in kernel/futex.c in the Linux kernel through 3.14.5 does not ensure that calls have two different futex addresses, which allows local users to gain privileges via a crafted FUTEX_REQUEUE command that facilitates unsafe waiter modification. La función futex_requeue en kernel/futex.c en el kernel de Linux hasta 3.14.5 no asegura que las llamadas tengan dos direcciones futex diferentes, lo que permite a usuarios locales ganar privilegios a través de un comando FUTEX_REQUEUE manipulado que facilita la modificación insegura del objeto o función a la espera. A flaw was found in the way the Linux kernel's futex subsystem handled the requeuing of certain Priority Inheritance (PI) futexes. A local, unprivileged user could use this flaw to escalate their privileges on the system. The futex_requeue function in kernel/futex.c in Linux kernel does not ensure that calls have two different futex addresses, which allows local users to gain privileges. • https://www.exploit-db.com/exploits/35370 https://github.com/timwr/CVE-2014-3153 https://github.com/lieanu/CVE-2014-3153 https://github.com/elongl/CVE-2014-3153 https://github.com/zerodavinci/CVE-2014-3153-exploit https://github.com/c3c/CVE-2014-3153 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=e9c243a5a6de0be8e584c604d353412584b592f8 http://linux.oracle.com/errata/ELSA-2014-0771.html http://linux.oracle.com/errata/ELSA-2014-3037.html •

https://notcve.org/view.php?id=CVE-2014-3917
kernel/auditsc.c in the Linux kernel through 3.14.5, when CONFIG_AUDITSYSCALL is enabled with certain syscall rules, allows local users to obtain potentially sensitive single-bit values from kernel memory or cause a denial of service (OOPS) via a large value of a syscall number. kernel/auditsc.c en el kernel de Linux hasta 3.14.5, cuando CONFIG_AUDITSYSCALL está habilitado con ciertas normas syscall, permite a usuarios locales obtener valores de un único bit potencialmente sensibles de la memoria del kernel o causar una denegación de servicio (OOPS) a través de un valor grande de un número syscall. An out-of-bounds memory access flaw was found in the Linux kernel's system call auditing implementation. On a system with existing audit rules defined, a local, unprivileged user could use this flaw to leak kernel memory to user space or, potentially, crash the system. • http://article.gmane.org/gmane.linux.kernel/1713179 http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://rhn.redhat.com/errata/RHSA-2014-1143.html http://rhn.redhat.com/errata/RHSA-2014-1281.html http://secunia.com/advisories/59777 http://secunia.com/advisories/60011 http://secunia.com/advisories/60564 http://www.openwall.com/lists/oss-security/2014/05/29/5 http://www.ubuntu.com/usn/USN-2334-1 http://www.ubuntu.com/usn/USN-2335-1& • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2014-3940
The Linux kernel through 3.14.5 does not properly consider the presence of hugetlb entries, which allows local users to cause a denial of service (memory corruption or system crash) by accessing certain memory locations, as demonstrated by triggering a race condition via numa_maps read operations during hugepage migration, related to fs/proc/task_mmu.c and mm/mempolicy.c. El kernel de Linux hasta 3.14.5 no considera debidamente la presencia de entradas hugetlb, lo que permite a usuarios locales causar una denegación de servicio (corrupción de memoria o caída de sistema) mediante el acceso a ciertas localizaciones de memoria, tal y como fue demostrado mediante el aprovechamiento de una condición de carrera a través de operaciones de lectura numa_maps durante la migración a hugepage, relacionado con fs/proc/task_mmu.c y mm/mempolicy.c. A flaw was found in the way Linux kernel's Transparent Huge Pages (THP) implementation handled non-huge page migration. A local, unprivileged user could use this flaw to crash the kernel by migrating transparent hugepages. • http://rhn.redhat.com/errata/RHSA-2015-0290.html http://rhn.redhat.com/errata/RHSA-2015-1272.html http://secunia.com/advisories/59011 http://secunia.com/advisories/61310 http://www.openwall.com/lists/oss-security/2014/06/02/5 http://www.securityfocus.com/bid/67786 https://bugzilla.redhat.com/show_bug.cgi?id=1104097 https://lkml.org/lkml/2014/3/18/784 https://support.f5.com/kb/en-us/solutions/public/15000/600/sol15685.html https://access.redhat.com/se • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
