CVSS: 7.8EPSS: 0%CPEs: 18EXPL: 9CVE-2014-3153 – Linux Kernel Privilege Escalation Vulnerability
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 •
CVSS: 4.7EPSS: 0%CPEs: 16EXPL: 0CVE-2014-3940 – Kernel: missing check during hugepage migration
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') •
CVSS: 4.7EPSS: 0%CPEs: 18EXPL: 0CVE-2014-3917 – kernel: DoS with syscall auditing
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-2014-1737
The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd device. La función raw_cmd_copyin en drivers/block/floppy.c en el kernel de Linux hasta 3.14.3 no maneja debidamente condiciones de error durante el procesado de una llamada FDRAWCMD ioctl, lo que permite a usuarios locales provocar operaciones kfree y ganar privilegios mediante el aprovechamiento de acceso de escritura hacia un dispositivo /dev/fd. A flaw was found in the way the Linux kernel's floppy driver handled user space provided data in certain error code paths while processing FDRAWCMD IOCTL commands. A local user with write access to /dev/fdX could use this flaw to free (using the kfree() function) arbitrary kernel memory. (CVE-2014-1737, Important) It was found that the Linux kernel's floppy driver leaked internal kernel memory addresses to user space during the processing of the FDRAWCMD IOCTL command. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ef87dbe7614341c2e7bfe8d32fcb7028cc97442c http://linux.oracle.com/errata/ELSA-2014-0771.html http://linux.oracle.com/errata/ELSA-2014-3043.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2014-05/msg00012.html http://rhn.redhat.com/errata/RHSA-2014-0800.html http://rhn.redhat.com/errata/RHSA-2014-0801.html http://secunia.com • CWE-754: Improper Check for Unusual or Exceptional Conditions •
