CVSS: 4.3EPSS: 0%CPEs: 8EXPL: 1CVE-2014-3601 – kernel: kvm: invalid parameter passing in kvm_iommu_map_pages()
https://notcve.org/view.php?id=CVE-2014-3601
The kvm_iommu_map_pages function in virt/kvm/iommu.c in the Linux kernel through 3.16.1 miscalculates the number of pages during the handling of a mapping failure, which allows guest OS users to (1) cause a denial of service (host OS memory corruption) or possibly have unspecified other impact by triggering a large gfn value or (2) cause a denial of service (host OS memory consumption) by triggering a small gfn value that leads to permanently pinned pages. La función kvm_iommu_map_pages en virt/kvm/iommu.c en el kernel de Linux hasta 3.16.1 calcula erróneamente el número de las páginas durante el manejo de un fallo en las asignaciones, lo que permite a usuarios del sistema operativo invitado (1) causar una denegación de servicio (corrupción de la memoria del sistema operativo anfitrión) o posiblemente tener otro impacto no especificado mediante la provocación de un valor gfn grande o (2) causar una denegación de servicio (corrupción de la memoria del sistema operativo anfitrión) mediante la provocación de un valor gfn pequeño que conduce a páginas fijadas (pinned) permanentemente. A flaw was found in the way the Linux kernel's kvm_iommu_map_pages() function handled IOMMU mapping failures. A privileged user in a guest with an assigned host device could use this flaw to crash the host. • http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=350b8bdd689cd2ab2c67c8a86a0be86cfa0751a7 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://secunia.com/advisories/60830 http://www.securityfocus.com/bid/69489 http://www.ubuntu.com/usn/USN-2356-1 http://www.ubuntu.com/usn/USN-2357&# • CWE-189: Numeric Errors •
CVSS: 2.1EPSS: 0%CPEs: 8EXPL: 0CVE-2014-0181 – kernel: net: insufficient permision checks of netlink messages
https://notcve.org/view.php?id=CVE-2014-0181
The Netlink implementation in the Linux kernel through 3.14.1 does not provide a mechanism for authorizing socket operations based on the opener of a socket, which allows local users to bypass intended access restrictions and modify network configurations by using a Netlink socket for the (1) stdout or (2) stderr of a setuid program. La implementación Netlink en el kernel de Linux hasta 3.14.1 no proporciona un mecanismo para autorizar operaciones socket basadas en el abridor de un socket, lo que permite a usuarios locales evadir restricciones de acceso y modificar configuraciones de red mediante el uso de un socket Netlink para (1) stdout o (2) stderr de un programa setuid. It was found that the permission checks performed by the Linux kernel when a netlink message was received were not sufficient. A local, unprivileged user could potentially bypass these restrictions by passing a netlink socket as stdout or stderr to a more privileged process and altering the output of this process. • 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://lists.opensuse.org/opensuse-security-announce/2015-04/msg00020.html http://marc.info/?l=linux-netdev&m=139828832919748&w=2 http://rhn.redhat.com/errata/RHSA-2014-1959.html http://www.open • CWE-264: Permissions, Privileges, and Access Controls •
