https://notcve.org/view.php?id=CVE-2014-3673
The SCTP implementation in the Linux kernel through 3.17.2 allows remote attackers to cause a denial of service (system crash) via a malformed ASCONF chunk, related to net/sctp/sm_make_chunk.c and net/sctp/sm_statefuns.c. La implementación SCTP en el kernel de Linux hasta 3.17.2 permite a atacantes remotos causar una denegación de servicio (caída del sistema) a través de un chunk ASCONF malformado, relacionado con net/sctp/sm_make_chunk.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 malformed 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=9de7922bc709eee2f609cd01d98aaedc4cf5ea74 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/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00020.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html • CWE-20: Improper Input Validation •

A certain Debian patch to the IPv6 implementation in the Linux kernel 3.2.x through 3.2.63 does not properly validate arguments in ipv6_select_ident function calls, which allows local users to cause a denial of service (NULL pointer dereference and system crash) by leveraging (1) tun or (2) macvtap device access. Cierto parche de Debian a la implementación IPv6 en el kernel de Linux 3.2.x hasta 3.2.63 no valida debidamente los argumentos en llamadas a la función ipv6_select_ident, lo que permite a usuarios locales causar una denegación de servicio (referencia a puntero nulo y caída del sistema) mediante el aprovechamiento del acceso al dispositivo (1) tun o (2) macvtap. • http://www.debian.org/security/2014/dsa-3060 http://www.openwall.com/lists/oss-security/2014/11/02/1 http://www.securityfocus.com/bid/70867 http://www.ubuntu.com/usn/USN-2417-1 http://www.ubuntu.com/usn/USN-2418-1 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=766195 •
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 •

https://notcve.org/view.php?id=CVE-2014-3610
The WRMSR processing functionality in the KVM subsystem in the Linux kernel through 3.17.2 does not properly handle the writing of a non-canonical address to a model-specific register, which allows guest OS users to cause a denial of service (host OS crash) by leveraging guest OS privileges, related to the wrmsr_interception function in arch/x86/kvm/svm.c and the handle_wrmsr function in arch/x86/kvm/vmx.c. La funcionalidad de procesamiento WRMSR en el subsistema KVM en el kernel de Linux hasta 3.17.2 no maneja debidamente la escritura de direcciones no canónicas en un registro especifico a modelos, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo anfitrión) mediante el aprovechamiento de los privilegios del sistema operativo invitado, relacionado con la función wrmsr_interception en arch/x86/kvm/svm.c y la función handle_wrmsr en arch/x86/kvm/vmx.c. It was found that KVM's Write to Model Specific Register (WRMSR) instruction emulation would write non-canonical values passed in by the guest to certain MSRs in the host's context. A privileged guest user could use this flaw to crash the host. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=854e8bb1aa06c578c2c9145fa6bfe3680ef63b23 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-2015-0869.html http://www.debian.org/security/2014/dsa-3060 http://www.openwall.com/lists/oss-security/2014/10/24/9 http://www.securityfocus.com/bid/70742 http://www.ubuntu.com/u • CWE-248: Uncaught Exception •

arch/x86/kvm/emulate.c in the KVM subsystem in the Linux kernel through 3.17.2 does not properly perform RIP changes, which allows guest OS users to cause a denial of service (guest OS crash) via a crafted application. arch/x86/kvm/emulate.c en el subsistema KVM en el kernel de Linux hasta 3.17.2 no realiza debidamente los cambios RIP, lo que permite a usuarios del sistema operativo invitado causar una denegación de servicio (caída del sistema operativo invitado) a través de una aplicación manipulada. A flaw was found in the way the Linux kernel's KVM subsystem handled non-canonical addresses when emulating instructions that change the RIP (for example, branches or calls). A guest user with access to an I/O or MMIO region could use this flaw to crash the guest. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=234f3ce485d54017f15cf5e0699cff4100121601 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=d1442d85cc30ea75f7d399474ca738e0bc96f715 http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2015-03/msg00025.html http://www.debian.org/security/2014/dsa-3060 http://www.openwall.com/lists/oss-security/2014/10/24/9 http:/ • CWE-248: Uncaught Exception •
