Description

Multiple serious vulnerabilities have been found in Microsoft Windows. Malicious users can exploit these vulnerabilities to gain privileges, cause a denial of service, obtain sensitive information, bypass security restrictions and execute arbitrary code.

Below is a complete list of vulnerabilities:

An incorrect handling of objects in memory in the Windows Graphics Device Interface (GDI) can be exploited locally to obtain sensitive information;
Multiple vulnerabilities in the Windows Kernel can be exploited locally via running a specially designed application to obtain sensitive information;
A memory corruption vulnerability in Microsoft Browsers can be exploited remotely via a specially designed website to execute arbitrary code;
An incorrect integrity-level validation in Microsoft Windows Storage can be exploited locally to bypass security restrictions;
An improper handling of embedded fonts in Microsoft font library can be exploited remotely via a specially designed website (web-based attack scenario) or document (file-sharing attack scenario) to execute arbitrary code;
An incorrect handling of DLL loading process in certain Windows components can be exploited locally to execute arbitrary code;
Multiple memory corruption vulnerabiltes in Windows Search can be exploited remotely via sending a specially designed messages to obtain sensitive information or execute arbitrary code;
An improper handling of DNS responses in Windows Domain Name System (DNS) can be exploited remotely by sending corrupted DNS response to the target to execute arbitrary code;
Multiple vulnerabilities in Microsoft Server Message Block server can be exploited remotely by sending a specially designed packet to the host to execute arbitrary code, cause denial of service, obtain sensitive information or gain privileges;
An incorrect handling of Advanced Local Procedure calls in Microsoft Windows can be exploited locally by running a specially designed application to gain privileges;
An unspecified vulnerability in Device Guard can be exploited locally by injecting malicious code into a script that is trusted by the Code Integrity policy to bypass securuty restrictions;
Multiple vulnerabilities in Windows Graphics component can be exploited locally via a specially crafted application to gain privileges or obtain sensitive information;
An incorrect enforcing of file sharing permissions in Windows Update Delivery Optimization can be exploited locally via creating a specially configued Delivery Optimization job to gain privileges;
An improper handling of objects in memory in Windows kernel-mode driver can be exploited locally via a specially designed application to gain privileges;
An incorrect handling of objects in memory in Windows Subsystem for Linux can be exploited locally via a specially designed application to cause denial of service;
Buffer overflow vulnerability in Microsoft JET Database Engine can be exploited via a specially designed Excel file to execute arbitrary code;
An improper accessing objects in memory in Microsoft Windows Text Services Framework can be exploited remotely via a specially designed website to execute arbitrary code.

Technical details

NB: Not every vulnerability already has CVSS rating, so cumulative CVSS rating can be not representative.

NB: At this moment Microsoft has just reserved CVE numbers for these vulnerabilities. Information can be changed soon.
