CVE-2014-4027 – Kernel: target/rd: imformation leakage
https://notcve.org/view.php?id=CVE-2014-4027
The rd_build_device_space function in drivers/target/target_core_rd.c in the Linux kernel before 3.14 does not properly initialize a certain data structure, which allows local users to obtain sensitive information from ramdisk_mcp memory by leveraging access to a SCSI initiator. La función rd_build_device_space en drivers/target/target_core_rd.c en el kernel de Linux anterior a 3.14 no inicializa debidamente cierta estructura de datos, lo que permite a usuarios locales obtener información sensible de la memoria ramdisk_mcp mediante el aprovechamiento del acceso a un iniciador SCSI. An information leak flaw was found in the RAM Disks Memory Copy (rd_mcp) backend driver of the iSCSI Target subsystem of the Linux kernel. A privileged user could use this flaw to leak the contents of kernel memory to an iSCSI initiator remote client. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=4442dc8a92b8f9ad8ee9e7f8438f4c04c03a22dc http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00007.html http://permalink.gmane.org/gmane.linux.scsi.target.devel/6618 http://secunia.com/advisories/59134 http://secunia.com/advisories/59777 http://secunia.com/advisories/60564 http://secunia.com/advisories/61310 http://www.openwall. • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2014-4157
https://notcve.org/view.php?id=CVE-2014-4157
arch/mips/include/asm/thread_info.h in the Linux kernel before 3.14.8 on the MIPS platform does not configure _TIF_SECCOMP checks on the fast system-call path, which allows local users to bypass intended PR_SET_SECCOMP restrictions by executing a crafted application without invoking a trace or audit subsystem. arch/mips/include/asm/thread_info.h en el kernel de Linux anterior a 3.14.8 en la plataforma MIPS no configura comprobaciones _TIF_SECCOMP en la ruta rápida de llamadas del sistema, lo que permite a usuarios locales evadir restricciones PR_SET_SECCOMP mediante la ejecución de una aplicación manipulada sin la invocación de una traza o un subsistema de auditoria. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=137f7df8cead00688524c82360930845396b8a21 http://openwall.com/lists/oss-security/2014/06/16/1 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.14.8 http://www.openwall.com/lists/oss-security/2014/06/17/17 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=751417 https://github.com/torvalds/linux/commit/137f7df8cead00688524c82360930845396b8a21 • CWE-264: Permissions, Privileges, and Access Controls •
CVE-2014-4014 – Linux Kernel 3.13 - SGID Privilege Escalation
https://notcve.org/view.php?id=CVE-2014-4014
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 •
CVE-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 •
CVE-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 •
