CVE-2017-2634 – kernel: dccp: crash while sending ipv6 reset packet
https://notcve.org/view.php?id=CVE-2017-2634
It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation before 2.6.22.17 used the IPv4-only inet_sk_rebuild_header() function for both IPv4 and IPv6 DCCP connections, which could result in memory corruptions. A remote attacker could use this flaw to crash the system. Se ha encontrado que la implementación del Protocolo de Control de Congestión de Datagramas (DCCP) del kernel de Linux en versiones anteriores a la 2.6.22.17 usaba la función inet_sk_rebuild_header() solo para IPv4 y conexiones DCCP IPv6, lo que podría resultar en corrupciones de memoria. Un atacante remoto podría utilizar este fallo para provocar un cierre inesperado del sistema.

CVE-2017-3157 – libreoffice: Arbitrary file disclosure in Calc and Writer
https://notcve.org/view.php?id=CVE-2017-3157
By exploiting the way Apache OpenOffice before 4.1.4 renders embedded objects, an attacker could craft a document that allows reading in a file from the user's filesystem. Information could be retrieved by the attacker by, e.g., using hidden sections to store the information, tricking the user into saving the document and convincing the user to send the document back to the attacker. The vulnerability is mitigated by the need for the attacker to know the precise file path in the target system, and the need to trick the user into saving the document and sending it back. Mediante la explotación de la forma en la que las versiones anteriores a la 4.1.4 de Apache OpenOffice renderizan objetos embebidos, un atacante podría manipular un documento que permite leer en un archivo del sistema de archivos del usuario. El atacante podría recuperar información mediante el uso de, por ejemplo, secciones ocultas para almacenar la información, engañando al usuario para que guarde el documento y convenciéndolo para que envíe de nuevo el documento al atacante. • http://www.securityfocus.com/bid/96402 http://www.securitytracker.com/id/1037893 https://access.redhat.com/errata/RHSA-2017:0914 https://access.redhat.com/errata/RHSA-2017:0979 https://www.debian.org/security/2017/dsa-3792 https://www.openoffice.org/security/cves/CVE-2017-3157.html https://access.redhat.com/security/cve/CVE-2017-3157 https://bugzilla.redhat.com/show_bug.cgi?id=1425844 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVE-2017-2618 – kernel: Off-by-one error in selinux_setprocattr (/proc/self/attr/fscreate)
https://notcve.org/view.php?id=CVE-2017-2618
A flaw was found in the Linux kernel's handling of clearing SELinux attributes on /proc/pid/attr files before 4.9.10. An empty (null) write to this file can crash the system by causing the system to attempt to access unmapped kernel memory. Se ha encontrado un fallo en el manejo del kernel de Linux para borrar los atributos SELinux de los ficheros /proc/pid/attr en versiones anteriores a la 4.9.10. Una escritura vacía (null) en este archivo puede cerrar de manera inesperada el sistema haciendo que el sistema intente acceder a la memoria no mapeada del kernel.

CVE-2017-2615 – Qemu: display: cirrus: oob access while doing bitblt copy backward mode
https://notcve.org/view.php?id=CVE-2017-2615
Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host.

CVE-2017-3135 – Combination of DNS64 and RPZ Can Lead to Crash
https://notcve.org/view.php?id=CVE-2017-3135
Under some conditions when using both DNS64 and RPZ to rewrite query responses, query processing can resume in an inconsistent state leading to either an INSIST assertion failure or an attempt to read through a NULL pointer. Affects BIND 9.8.8, 9.9.3-S1 -> 9.9.9-S7, 9.9.3 -> 9.9.9-P5, 9.9.10b1, 9.10.0 -> 9.10.4-P5, 9.10.5b1, 9.11.0 -> 9.11.0-P2, 9.11.1b1. En ciertas condiciones, al emplear DNS64 y RPZ para rescribir respuestas a consultas, el procesamiento de consultas puede continuar de forma inconsistente, lo que puede conducir a un fallo de aserción de INSIST o a un intento para leer a través de un puntero NULL. Afecta a BIND en su versión 9.8.8, desde la versión 9.9.3-S1 hasta la 9.9.9-S7, desde la versión 9.9.3 hasta la 9.9.9-P5, la versión 9.9.10b1, desde la versión 9.10.0 hasta la 9.10.4-P5, la versión 9.10.5b1, desde la versión 9.11.0 hasta la 9.11.0-P2 y a la versión 9.11.1b1. A denial of service flaw was found in the way BIND handled query responses when both DNS64 and RPZ were used. • http://rhn.redhat.com/errata/RHSA-2017-0276.html http://www.securityfocus.com/bid/96150 http://www.securitytracker.com/id/1037801 https://h20566.www2.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03747en_us https://kb.isc.org/docs/aa-01453 https://security.gentoo.org/glsa/201708-01 https://security.netapp.com/advisory/ntap-20180926-0005 https://www.debian.org/security/2017/dsa-3795 https://access.redhat.com/security/cve/CVE-2017-3135 https:/ • CWE-476: NULL Pointer Dereference •
