CVSS: 4.9EPSS: 0%CPEs: 1EXPL: 0CVE-2014-2673 – kernel: powerpc: tm: crash when forking inside a transaction
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 •

https://notcve.org/view.php?id=CVE-2013-7339
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. A NULL pointer dereference flaw was found in the rds_ib_laddr_check() function in the Linux kernel's implementation of Reliable Datagram Sockets (RDS). A local, unprivileged user could use this flaw to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=c2349758acf1874e4c2b93fe41d072336f1a31d0 http://secunia.com/advisories/59386 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.12.8 http://www.openwall.com/lists/oss-security/2014/03/20/14 http://www.securityfocus.com/bid/66351 https://bugzilla.redhat.com/show_bug.cgi?id=1079214 https://github.com/torvalds/linux/commit/c2349758acf1874e4c2b93fe41d072336f1a31d0 https://access.redhat.com/security/cve/CVE&# • CWE-476: NULL Pointer Dereference •

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 sctp_sf_do_5_1D_ce function in net/sctp/sm_statefuns.c in the Linux kernel through 3.13.6 does not validate certain auth_enable and auth_capable fields before making an sctp_sf_authenticate call, which allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via an SCTP handshake with a modified INIT chunk and a crafted AUTH chunk before a COOKIE_ECHO chunk. La función sctp_sf_do_5_1D_ce en net/sctp/sm_statefuns.c en el kernel de Linux hasta la versión 3.13.6 no valida ciertos campos auth_enable y auth_capable antes de hacer una llamada sctp_sf_authenticate, lo que permite a atacantes remotos provocar una denegación de servicio (referencia a puntero NULL y caída del sistema) a través de un SCTP handshake con un fragmento INIT modificado y un fragmento AUTH manipulado anterior a un fragmento COOKIE_ECHO. A flaw was found in the way the Linux kernel processed an authenticated COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote attacker could use this flaw to crash the system by initiating a specially crafted SCTP handshake in order to trigger a NULL pointer dereference on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ec0223ec48a90cb605244b45f7c62de856403729 http://rhn.redhat.com/errata/RHSA-2014-0328.html http://rhn.redhat.com/errata/RHSA-2014-0419.html http://rhn.redhat.com/errata/RHSA-2014-0432.html http://secunia.com/advisories/59216 http://support.f5.com/kb/en-us/solutions/public/15000/300/sol15317.html http://www.openwall.com/lists/oss-security/2014/03/04/6 http://www.securityfocus.com/bid/65943 h • CWE-476: NULL Pointer Dereference •
