https://notcve.org/view.php?id=CVE-2017-2626
It was discovered that libICE before 1.0.9-8 used a weak entropy to generate keys. A local attacker could potentially use this flaw for session hijacking using the information available from the process list. Se ha descubierto que libICE en versiones anteriores a la 1.0.9-8 usaba una entropía débil para generar claves. Un atacante local podría utilizar este fallo para secuestrar sesiones utilizando la información disponible en la lista de procesos.

Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. Quick emulator (QEMU) en versiones anteriores a la 2.8 construido con el soporte del emulador Cirrus CLGD 54xx VGA Emulator es vulnerable a un problema de acceso fuera de límites.

CVSS: 5.5EPSS: 0%CPEs: 18EXPL: 0CVE-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 •

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.
