CVSS: 5.5EPSS: 0%CPEs: 13EXPL: 0CVE-2014-3690 – kernel: kvm: vmx: invalid host cr4 handling across vm entries
https://notcve.org/view.php?id=CVE-2014-3690
arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU. arch/x86/kvm/vmx.c en el subsistema KVM en el kernel de Linux anterior a 3.17.2 en los procesadores Intel no asegura que el valor en el registro de control CR4 queda igual después de una entrada VM, lo que permite a usuarios del sistema operativo anfitrión cancelar varios procesos o causar una denegación de servicio (interrupción del sistema) mediante el aprovechamiento del acceso a /dev/kvm, tal y como fue demostrado por llamadas a prctl PR_SET_TSC dentro de una copia modificada de QEMU. It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=d974baa398f34393db76be45f7d4d04fbdbb4a0a 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/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2015-04/msg00015.html http://rhn.redhat.com/errata/RHSA-2015-0290.html http://rhn.redhat.com/errata/RHSA&# • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.8EPSS: 3%CPEs: 20EXPL: 1CVE-2014-3687 – kernel: net: sctp: fix panic on duplicate ASCONF chunks
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 •
