CVE-2016-3990 – libtiff: out-of-bounds write in horizontalDifference8()
https://notcve.org/view.php?id=CVE-2016-3990
Heap-based buffer overflow in the horizontalDifference8 function in tif_pixarlog.c in LibTIFF 4.0.6 and earlier allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted TIFF image to tiffcp. Desbordamiento de búfer basado en memoria dinámica en la función horizontalDifference8 en tif_pixarlog.c en LibTIFF 4.0.6 y versiones anteriores permite a atacantes remotos provocar una denegación de servicio (caída) o ejecutar código arbitrario a través de una imagen TIFF manipulada para tiffcp. • http://bugzilla.maptools.org/show_bug.cgi?id=2544 http://lists.opensuse.org/opensuse-updates/2016-09/msg00039.html http://rhn.redhat.com/errata/RHSA-2016-1546.html http://rhn.redhat.com/errata/RHSA-2016-1547.html http://www.debian.org/security/2017/dsa-3762 http://www.openwall.com/lists/oss-security/2016/04/12/2 http://www.oracle.com/technetwork/topics/security/linuxbulletinjul2016-3090544.html http://www.oracle.com/technetwork/topics/security/ovmbulletinjul2016-3090546.html http: • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-787: Out-of-bounds Write •
CVE-2016-5403 – Qemu: virtio: unbounded memory allocation on host via guest leading to DoS
https://notcve.org/view.php?id=CVE-2016-5403
The virtqueue_pop function in hw/virtio/virtio.c in QEMU allows local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) by submitting requests without waiting for completion. La función virtqueue_pop en hw/virtio/virtio.c en QEMU permite a administradores locales del SO invitado provocar una denegación de servicio (consumo de memoria y caida del proceso QUEMU) mediante la presentación de solicitudes sin esperar la finalización. Quick Emulator (QEMU) built with the virtio framework is vulnerable to an unbounded memory allocation issue. It was found that a malicious guest user could submit more requests than the virtqueue size permits. Processing a request allocates a VirtQueueElement results in unbounded memory allocation on the host controlled by the guest. • http://rhn.redhat.com/errata/RHSA-2016-1585.html http://rhn.redhat.com/errata/RHSA-2016-1586.html http://rhn.redhat.com/errata/RHSA-2016-1606.html http://rhn.redhat.com/errata/RHSA-2016-1607.html http://rhn.redhat.com/errata/RHSA-2016-1652.html http://rhn.redhat.com/errata/RHSA-2016-1653.html http://rhn.redhat.com/errata/RHSA-2016-1654.html http://rhn.redhat.com/errata/RHSA-2016-1655.html http://rhn.redhat.com/errata/RHSA-2016-1756.html http://rhn • CWE-400: Uncontrolled Resource Consumption •
CVE-2016-4470 – kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path
https://notcve.org/view.php?id=CVE-2016-4470
The key_reject_and_link function in security/keys/key.c in the Linux kernel through 4.6.3 does not ensure that a certain data structure is initialized, which allows local users to cause a denial of service (system crash) via vectors involving a crafted keyctl request2 command. La función key_reject_and_link en security/keys/key.c en el kernel de Linux hasta la versión 4.6.3 no asegura que cierta estructura de datos esté inicializada, lo que permite a usuarios locales provocar una denegación de servicio (caída del sistema) a través de vectores involucrando un comando keyctl request2 manipulado. A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free condition on the system, potentially allowing for privilege escalation. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=38327424b40bcebe2de92d07312c89360ac9229a http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00000.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00003.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2016-08/msg00009.html http://lists.opensuse.org • CWE-253: Incorrect Check of Function Return Value •
