CVE-2020-16914 – Windows GDI+ Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2020-16914
<p>An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface Plus (GDI+) handles objects in memory, allowing an attacker to retrieve information from a targeted system. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability.</p> <p>To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application.</p> <p>The security update addresses the vulnerability by correcting how GDI+ handles memory addresses.</p> Se presenta una vulnerabilidad de divulgación de información en la manera que Windows Graphics Device Interface Plus (GDI+) maneja objetos en memoria, permitiendo a un atacante recuperar información de un sistema apuntado, también se conoce como "Windows GDI+ Information Disclosure Vulnerability" • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-16914 •
CVE-2020-16912 – Windows Backup Service Elevation of Privilege Vulnerability
https://notcve.org/view.php?id=CVE-2020-16912
<p>An elevation of privilege vulnerability exists when the Windows Backup Service improperly handles file operations.</p> <p>To exploit this vulnerability, an attacker would first have to gain execution on the victim system. An attacker could then run a specially crafted application to elevate privileges.</p> <p>The security update addresses the vulnerability by correcting how the Windows Backup Service handles file operations.</p> Se presenta una vulnerabilidad de escalada de privilegios cuando el Windows Backup Service maneja inapropiadamente operaciones de archivos. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-16912 •
CVE-2020-16913 – Win32k Elevation of Privilege Vulnerability
https://notcve.org/view.php?id=CVE-2020-16913
<p>An elevation of privilege vulnerability exists in Windows when the Windows kernel-mode driver fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.</p> <p>To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-16913 •
CVE-2020-16910 – Windows Security Feature Bypass Vulnerability
https://notcve.org/view.php?id=CVE-2020-16910
<p>A security feature bypass vulnerability exists when Microsoft Windows fails to handle file creation permissions, which could allow an attacker to create files in a protected Unified Extensible Firmware Interface (UEFI) location.</p> <p>To exploit this vulnerability, an attacker could run a specially crafted application to bypass Unified Extensible Firmware Interface (UEFI) variable security in Windows.</p> <p>The security update addresses the vulnerability by correcting security feature behavior to enforce permissions.</p> Se presenta una vulnerabilidad de omisión de la característica de seguridad cuando Microsoft Windows presenta un fallo al manejar permisos de creación de archivos, lo que podría permitir a un atacante crear archivos en una ubicación protegida de Unified Extensible Firmware Interface (UEFI). Para explotar esta vulnerabilidad, un atacante podría correr una aplicación especialmente diseñada para omitir la seguridad variable de Unified Extensible Firmware Interface (UEFI) en Windows. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-16910 • CWE-281: Improper Preservation of Permissions •
CVE-2020-16911 – GDI+ Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-16911
<p>A remote code execution vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in the memory. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.</p> <p>There are multiple ways an attacker could exploit the vulnerability:</p> <ul> <li>In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability and then convince users to view the website. • https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-16911 •
