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 •

CVSS: 5.0EPSS: 4%CPEs: 1EXPL: 0CVE-2015-8215 – kernel: MTU value is not validated in IPv6 stack causing packet loss
https://notcve.org/view.php?id=CVE-2015-8215
net/ipv6/addrconf.c in the IPv6 stack in the Linux kernel before 4.0 does not validate attempted changes to the MTU value, which allows context-dependent attackers to cause a denial of service (packet loss) via a value that is (1) smaller than the minimum compliant value or (2) larger than the MTU of an interface, as demonstrated by a Router Advertisement (RA) message that is not validated by a daemon, a different vulnerability than CVE-2015-0272. NOTE: the scope of CVE-2015-0272 is limited to the NetworkManager product. net/ipv6/addrconf.c en la pila IPv6 en el kernel Linux en versiones anteriores a 4.0 no valida los intentos de cambio del valor MTU, lo que permite a atacantes dependientes del contexto causar una denegación de servicio (pérdida de paquetes) a través de un valor que es (1) menor que el valor mínimo compatible o (2) más grande que la MTU de una interfaz, según lo demostrado por un mensaje Router Advertisement (RA) que no es validado por un demonio, una vulnerabilidad diferente a CVE-2015-0272. NOTA: el alcance de CVE-2015-0272 se limita al producto NetworkManager. It was found that the Linux kernel's IPv6 network stack did not properly validate the value of the MTU variable when it was set. A remote attacker could potentially use this flaw to disrupt a target system's networking (packet loss) by setting an invalid MTU value, for example, via a NetworkManager daemon that is processing router advertisement packets running on the target system. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=77751427a1ff25b27d47a4c36b12c3c8667855ac http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00018.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2015-12/msg00031.html http://lists.opensuse.org/opensuse-security-announce/2016-02/msg00013.html http://lists.opensuse.org • CWE-20: Improper Input Validation •
