CVSS: 7.8EPSS: 0%CPEs: 9EXPL: 1CVE-2014-7826 – kernel: insufficient syscall number validation in perf and ftrace subsystems
https://notcve.org/view.php?id=CVE-2014-7826
kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the ftrace subsystem, which allows local users to gain privileges or cause a denial of service (invalid pointer dereference) via a crafted application. kernel/trace/trace_syscalls.c en el kernel de Linux hasta 3.17.2 no maneja debidamente los números privados de las llamadas al sistema durante el uso del subsistema ftrace, lo que permite a usuarios locales ganar privilegios o causar una denegación de servicio (referencia a puntero inválido) a través de una aplicación manipulada. An out-of-bounds memory access flaw, CVE-2014-7825, was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system. Additionally, an out-of-bounds memory access flaw, CVE-2014-7826, was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=086ba77a6db00ed858ff07451bedee197df868c9 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://rhn.redhat.com/errata/RHSA-2014-1943.html http://rhn.redhat.com/errata/RHSA-2015-0290.html http://rhn.redhat.com/errata/RHSA-2015-0864.html http://www.openwall.com/lists/oss-security/2014/11/06/11 http:// • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2014-3687
The sctp_assoc_lookup_asconf_ack function in net/sctp/associola.c in the SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (panic) via duplicate ASCONF chunks that trigger an incorrect uncork within the side-effect interpreter. La función sctp_assoc_lookup_asconf_ack en net/sctp/associola.c en la implementación SCTP en el kernel de Linux hasta 3.17.2 permite a atacantes remotos causar una denegación de servicio (kernel panic) a través de trozos ASCONF duplicados que provocan una liberación incorrecta dentro del intérprete de efectos secundarios. A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled duplicate Address Configuration Change Chunks (ASCONF). A remote attacker could use either of these flaws to crash the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=b69040d8e39f20d5215a03502a8e8b4c6ab78395 http://linux.oracle.com/errata/ELSA-2014-3087.html http://linux.oracle.com/errata/ELSA-2014-3088.html http://linux.oracle.com/errata/ELSA-2014-3089.html http://lists.opensuse.org/opensuse-security-announce/2015-01/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html • CWE-400: Uncontrolled Resource Consumption •

CVSS: 7.1EPSS: 20%CPEs: 204EXPL: 1CVE-2014-3688 – kernel: net: sctp: remote memory pressure from excessive queueing
https://notcve.org/view.php?id=CVE-2014-3688
The SCTP implementation in the Linux kernel before 3.17.4 allows remote attackers to cause a denial of service (memory consumption) by triggering a large number of chunks in an association's output queue, as demonstrated by ASCONF probes, related to net/sctp/inqueue.c and net/sctp/sm_statefuns.c. La implementación SCTP en el kernel de Linux anterior a 3.17.4 permite a atacantes remotos causar una denegación de servicio (consumo de memoria) mediante la provocación de un gran número de trozos (chunks) en la cola de salidas de una asociación, tal y como fue demostrado por sondas ASCONF, relacionado con net/sctp/inqueue.c y net/sctp/sm_statefuns.c. A flaw was found in the way the Linux kernel's Stream Control Transmission Protocol (SCTP) implementation handled the association's output queue. A remote attacker could send specially crafted packets that would cause the system to use an excessive amount of memory, leading to a denial of service. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=26b87c7881006311828bb0ab271a551a62dcceb4 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://marc.info/?l=bugtraq&m=142722450701342&w=2 http://marc.info/?l=bugtraq& • CWE-399: Resource Management Errors •
