The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel through 4.3.3 do not verify an address length, which allows local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application. Las funciones (1) pptp_bind y (2) pptp_connect en drivers/net/ppp/pptp.c en el kernel de Linux hasta la versión 4.3.3 no verifican la longitud de una dirección, lo que permite a usuarios locales obtener información sensible de la memoria del kernel y eludir el mecanismo de protección KASLR a través de una aplicación manipulada. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=09ccfd238e5a0e670d8178cf50180ea81ae09ae1 http://lists.fedoraproject.org/pipermail/package-announce/2016-February/176484.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00038.html http://twitter.com/grsecurity/statuses/676744240802750464 http://www.debian.org/security/2016/d • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

The PCI backend driver in Xen, when running on an x86 system and using Linux 3.1.x through 4.3.x as the driver domain, allows local guest administrators to hit BUG conditions and cause a denial of service (NULL pointer dereference and host OS crash) by leveraging a system with access to a passed-through MSI or MSI-X capable physical PCI device and a crafted sequence of XEN_PCI_OP_* operations, aka "Linux pciback missing sanity checks." El controlador backend PCI en Xen, cuando se ejecuta en un sistema x86 y utiliza Linux 3.1.x hasta la versión 4.3.x como dominio de controlador, permite a administradores locales invitados alcanzar condiciones de BUG y provocar una denegación de servicio (referencia a puntero NULL y caída de SO anfitrión) aprovechando un sistema con acceso a un dispositivo físico PCI capaz de pasar a través de MSI o MSI-X y una secuencia de operaciones XEN_PCI_OP_* manipulada, también conocido como "Linux pciback missing sanity checks". • http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2016-06/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2016-07/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00044.html http://lists.opensuse.org/opensuse-security-announce/2016-08 • CWE-476: NULL Pointer Dereference •

Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel before 4.3.3 allows local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls. Vulnerabilidad de uso después de la liberación de la memoria en net/unix/af_unix.c en el kernel de Linux en versiones anteriores a 4.3.3 permite a usuarios locales eludir los permisos destinados al socket AF_UNIX o provocar una denegación de servicio (panic) a través de llamadas epoll_ctl manipuladas. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=7d267278a9ece963d77eefec61630223fce08c6c http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00033.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00034.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00037.html http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00038.html http://lists.opensuse.org •
CVSS: 4.0EPSS: 0%CPEs: 1EXPL: 0CVE-2015-8374 – kernel: Information leak when truncating of compressed/inlined extents on BTRFS
https://notcve.org/view.php?id=CVE-2015-8374
fs/btrfs/inode.c in the Linux kernel before 4.3.3 mishandles compressed inline extents, which allows local users to obtain sensitive pre-truncation information from a file via a clone action. fs/btrfs/inode.c en el kernel de Linux en versiones anteriores a 4.3.3 no maneja correctamente extensiones en línea comprimidas, lo que permite a usuarios locales obtener información sensible previa al truncamiento desde un archivo a través de una acción clone. An information-leak vulnerability was found in the kernel when it truncated a file to a smaller size which consisted of an inline extent that was compressed. The data between the new file size and the old file size was not discarded and the number of bytes used by the inode were not correctly decremented, which gave the wrong report for callers of the stat(2) syscall. This wasted metadata space and allowed for the truncated data to be leaked, and data corruption or loss to occur. A caller of the clone ioctl could exploit this flaw by using only standard file-system operations without root access to read the truncated data. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=0305cd5f7fca85dae392b9ba85b116896eb7c1c7 http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http://www.debian.org/security/2015/dsa-3426 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.3.3 http://www.openwall.com/lists/oss-security/2015/11/27/2 http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html http://www.oracle.co • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2015-8543
The networking implementation in the Linux kernel through 4.3.3, as used in Android and other products, does not validate protocol identifiers for certain protocol families, which allows local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support to execute a crafted SOCK_RAW application. La implementación de redes en el kernel de Linux hasta la versión 4.3.3, tal como se utiliza en Android y otros productos, no valida identificadores de protocolo para ciertas familias de protocolos, lo que permite a usuarios locales provocar una denegación de servicio (referencia a puntero de función NULL y caída de sistema) o posiblemente obtener privilegios mediante el aprovechamiento de soporte CLONE_NEWUSER para ejecutar una aplicación SOCK_RAW manipulada. A NULL pointer dereference flaw was found in the way the Linux kernel's network subsystem handled socket creation with an invalid protocol identifier. A local user could use this flaw to crash the system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=79462ad02e861803b3840cc782248c7359451cd9 http://lists.opensuse.org/opensuse-security-announce/2016-03/msg00094.html http://lists.opensuse.org/opensuse-security-announce/2016-04/msg00045.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00038.html http://rhn.redhat.com/errata/RHSA-2016-0855.html http://rhn.redhat.com/errata/RHSA-2016-2574.html http://rhn.redhat.com/errata/RHSA-2016-2584.html http:// • CWE-476: NULL Pointer Dereference •
