https://notcve.org/view.php?id=CVE-2014-2309
The ip6_route_add function in net/ipv6/route.c in the Linux kernel through 3.13.6 does not properly count the addition of routes, which allows remote attackers to cause a denial of service (memory consumption) via a flood of ICMPv6 Router Advertisement packets. La función ip6_route_add en net/ipv6/route.c en el kernel de Linux hasta 3.13.6 no cuenta debidamente la suma de rutas, lo que permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de una inundación de paquetes de ICMPv6 Router Advertisement. • http://git.kernel.org/cgit/linux/kernel/git/davem/net.git/commit/?id=c88507fbad8055297c1d1e21e599f46960cbee39 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://secunia.com/advisories/57250 http://www.openwall.com/lists/oss-security/2014/03/08/1 http://www.securityfocus.com/bid/66095 http://www.securitytracker.com/id/1029894 https://access.redhat.com/security/cve/CVE-2014-2309 https: • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

https://notcve.org/view.php?id=CVE-2014-0101
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 •

Buffer overflow in the complete_emulated_mmio function in arch/x86/kvm/x86.c in the Linux kernel before 3.13.6 allows guest OS users to execute arbitrary code on the host OS by leveraging a loop that triggers an invalid memory copy affecting certain cancel_work_item data. Desbordamiento de buffer en la función complete_emulated_mmio en arch/x86/kvm/x86.c en el kernel de Linux anterior a 3.13.6 permite a usuarios del sistema operativo invitado ejecutar código arbitrario en el sistema operativo anfitrión mediante el aprovechamiento de un bucle que provoca una copia de memoria inválida que afecta a ciertos datos cancel_work_item. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a08d3b3b99efd509133946056531cdf8f3a0c09b http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.13.6 http://www.openwall.com/lists/oss-security/2014/03/03/1 https://bugzilla.redhat.com/show_bug.cgi?id=1062368 https://github.com/torvalds/linux/commit/a08d3b3b99efd509133946056531cdf8f3a0c09b • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

The nfs_can_extend_write function in fs/nfs/write.c in the Linux kernel before 3.13.3 relies on a write delegation to extend a write operation without a certain up-to-date verification, which allows local users to obtain sensitive information from kernel memory in opportunistic circumstances by writing to a file in an NFS filesystem and then reading the same file. La función nfs_can_extend_write en fs/nfs/write.c en el kernel de Linux anterior a 3.13.3 se basa en una delegación de escritura para extender una operación de escritura sin cierta verificación actualizada, lo que permite a usuarios locales obtener información sensible de la memoria del kernel en circunstancias oportunistas mediante la escritura a un archivo en un sistema de archivos NFS y luego leyendo el mismo archivo. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=263b4509ec4d47e0da3e753f85a39ea12d1eff24 http://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.13.3 http://www.openwall.com/lists/oss-security/2014/02/20/16 http://www.ubuntu.com/usn/USN-2137-1 http://www.ubuntu.com/usn/USN-2140-1 https://bugzilla.redhat.com/show_bug.cgi?id=1066939 https://github.com/torvalds/linux/commit/263b4509ec4d47e0da3e753f85a39ea12d1eff24 https://access.redhat.com/security& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
