CVSS: 6.5EPSS: 0%CPEs: 8EXPL: 1CVE-2017-2625 – libXdmcp: weak entropy usage for session keys
https://notcve.org/view.php?id=CVE-2017-2625
It was discovered that libXdmcp before 1.1.2 including used weak entropy to generate session keys. On a multi-user system using xdmcp, a local attacker could potentially use information available from the process list to brute force the key, allowing them to hijack other users' sessions. Se ha descubierto que libXdmcp en versiones anteriores a la 1.1.2 usaba entropía débil para generar claves de sesión. En un sistema multiusuario que utilice xdmcp, un atacante local podría utilizar la información disponible en la lista de procesos para usar un ataque de fuerza bruta en la clave, permitiéndole secuestrar las sesiones de otros usuarios. It was discovered that libXdmcp used weak entropy to generate session keys. • http://www.securityfocus.com/bid/96480 http://www.securitytracker.com/id/1037919 https://access.redhat.com/errata/RHSA-2017:1865 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-2625 https://cgit.freedesktop.org/xorg/lib/libXdmcp/commit/?id=0554324ec6bbc2071f5d1f8ad211a1643e29eb1f https://lists.debian.org/debian-lts-announce/2019/11/msg00024.html https://security.gentoo.org/glsa/201704-03 https://www.x41-dsec.de/lab/advisories/x41-2017-001-xorg https://access.redhat.com/security& • CWE-320: Key Management Errors CWE-331: Insufficient Entropy •

https://notcve.org/view.php?id=CVE-2017-2620
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 •
