fs/namespace.c in the Linux kernel before 4.0.2 processes MNT_DETACH umount2 system calls without verifying that the MNT_LOCKED flag is unset, which allows local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user namespace. fs/namespace.c en el kernel de Linux en versiones anteriores a 4.0.2 procesa llamadas de sistema MNT_DETACH umount2 sin verificar que el indicador MNT_LOCKED no está establecido, lo que permite a usuarios locales eludir restricciones dedicadas al acceso y navegar a localizaciones de archivos de sistema bajo un montaje llamando a umount2 en un espacio de nombres de usuario. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ce07d891a0891d3c0d0c2d73d577490486b809e1 http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00056.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.0.2 http://www.openwall.com/lists/oss-security/2015/04/17/4 http://www.securityfocus.com/bid/742 • CWE-284: Improper Access Control •

CVSS: 5.5EPSS: 0%CPEs: 14EXPL: 0CVE-2016-3156 – kernel: ipv4: denial of service when destroying a network interface
https://notcve.org/view.php?id=CVE-2016-3156
The IPv4 implementation in the Linux kernel before 4.5.2 mishandles destruction of device objects, which allows guest OS users to cause a denial of service (host OS networking outage) by arranging for a large number of IP addresses. La implementación IPv4 en el kernel de Linux en versiones anteriores a 4.5.2 no maneja adecuadamente la destrucción de objetos de dispositivo, lo que permite a usuarios del SO invitado provocar una denegación de servicio (corte de la red del sistema operativo anfitrión) disponiendo un gran número de direcciones IP. A security flaw was found in the Linux kernel's networking subsystem that destroying the network interface with huge number of ipv4 addresses assigned keeps "rtnl_lock" spinlock for a very long time (up to hour). This blocks many network-related operations, including creation of new incoming ssh connections. The problem is especially important for containers, as the container owner has enough permissions to trigger this and block a network access on a whole host, outside the container. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=fbd40ea0180a2d328c5adc61414dc8bab9335ce2 http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2016-05/msg00060.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00054.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00059.html http://lists.opensuse.org • CWE-399: Resource Management Errors CWE-400: Uncontrolled Resource Consumption •
