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.

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 •

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 •
