CVE-2014-4508 – Kernel: x86_32: BUG in syscall auditing
https://notcve.org/view.php?id=CVE-2014-4508
arch/x86/kernel/entry_32.S in the Linux kernel through 3.15.1 on 32-bit x86 platforms, when syscall auditing is enabled and the sep CPU feature flag is set, allows local users to cause a denial of service (OOPS and system crash) via an invalid syscall number, as demonstrated by number 1000. arch/x86/kernel/entry_32.S en el kernel de Linux hasta 3.15.1 en plataformas de 32-bit x86, cuando la auditoria de llamadas de sistema está habilitada y la etiqueta de la funcionalidad de la CPU sep está configurada, permite a usuarios locales causar una denegación de servicio (OOPS y caída del sistema) a través de un número de llamada de sistema inválido, tal y como fue demostrado por el número 1000. A flaw was found in the Linux kernel’s system-call auditing support(CONFIG_AUDITSYSCALL) for 32-bit platforms. It is vulnerable to a crash caused by erroneous handling of bad system call numerals. This issue occurs during syscall(2) calls if system-call auditing is enabled on the system. This flaw allows an unprivileged user or process to crash the system kernel, resulting in a denial of service. • http://article.gmane.org/gmane.linux.kernel/1726110 http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2014-10/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://openwall.com/lists/oss-security/2014/06/20/1 http://secunia.com/advisories/58964 http://secunia.com/advisories/60564 http://www.openwall.com/lists/oss-security/2014/06/20/10 http://www.openwall.com • CWE-189: Numeric Errors CWE-391: Unchecked Error Condition •
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 •
