https://notcve.org/view.php?id=CVE-2014-2673
The arch_dup_task_struct function in the Transactional Memory (TM) implementation in arch/powerpc/kernel/process.c in the Linux kernel before 3.13.7 on the powerpc platform does not properly interact with the clone and fork system calls, which allows local users to cause a denial of service (Program Check and system crash) via certain instructions that are executed with the processor in the Transactional state. La función arch_dup_task_struct en la implementación Transactional Memory (TM) en arch/powerpc/kernel/process.c en el kernel de Linux anterior a 3.13.7 en la plataforma powerpc no interactúa debidamente con las llamadas de sistema clon y fork, lo que permite a usuarios locales causar una denegación de servicio (comprobación de programa y caída de sistema) a través de ciertas instrucciones que son ejecutadas con el procesador en el estado transaccional. A flaw was found in the way the Linux kernel performed forking inside of a transaction. A local, unprivileged user on a PowerPC system that supports transactional memory could use this flaw to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=621b5060e823301d0cba4cb52a7ee3491922d291 http://secunia.com/advisories/57436 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.13.7 http://www.openwall.com/lists/oss-security/2014/03/30/5 http://www.securityfocus.com/bid/66477 https://exchange.xforce.ibmcloud.com/vulnerabilities/92113 https://github.com/torvalds/linux/commit/621b5060e823301d0cba4cb52a7ee3491922d291 https://www.kernel.org/pub/linux/kernel/ • CWE-20: Improper Input Validation •

net/netfilter/nf_conntrack_proto_dccp.c in the Linux kernel through 3.13.6 uses a DCCP header pointer incorrectly, which allows remote attackers to cause a denial of service (system crash) or possibly execute arbitrary code via a DCCP packet that triggers a call to the (1) dccp_new, (2) dccp_packet, or (3) dccp_error function. net/netfilter/nf_conntrack_proto_dccp.c en el kernel de Linux hasta 3.13.6 utiliza un puntero de cabecera DCCP incorrectamente, lo que permite a atacantes remotos causar una denegación de servicio (caída de sistema) o posiblemente ejecutar código arbitrario a través de un paquete DCCP que provoca una llamada la función (1) dccp_new, (2) dccp_packet o (3) dccp_error. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b22f5126a24b3b2f15448c3f2a254fc10cbc2b92 http://secunia.com/advisories/57446 http://twitter.com/grsecurity/statuses/445496197399461888 http://www.openwall.com/lists/oss-security/2014/03/17/7 http://www.securityfocus.com/bid/66279 http://www.securitytracker.com/id/1029945 http://www.ubuntu.com/usn/USN-2173-1 http://www.ubuntu.com/usn/USN-2174-1 https://bugzilla.redhat.com/show_bug.cgi?id=1077343 • CWE-20: Improper Input Validation •

The rds_ib_laddr_check function in net/rds/ib.c in the Linux kernel before 3.12.8 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a bind system call for an RDS socket on a system that lacks RDS transports. La función rds_ib_laddr_check en net/rds/ib.c en el kernel de Linux anterior a 3.12.8 permite a usuarios locales causar una denegación de servicio (referencia de puntero nulo y caída de sistema) o posiblemente tener otro impacto no especificado a través de una llamada de sistema bind para un socket RDS en un sistema que carece de transportes RDS.
