Multiple vulnerabilities in Microsoft Windows

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

Below is a complete list of vulnerabilities:

1. An incorrect input data handling in Cortana can be exploited locally via specially designed commands to gain privileges;
2. An improper parsing of HTTP 2.0 requests in HTTP.sys can be exploited remotely via specially designed HTTP packet to cause denial of service;
3. Incorrect operation of the hashing algorithm in Windows Code Integrity Module can be exploited remotely via a specially designed e-mail message to cause denial of service;
4. Multiple security bypass vulnerabilities in Device Guard can be exploited locally to bypass security restrictions;
5. Improper handling of objects in memory in Microsoft Windows can be exploited locally via a specially crafted application to cause denial of service;
6. Incorrect privilege levels enforcing in Windows Hyper-V can be exploited locally via unspecified attack vector to gain privileges;
7. Improper handling of objects in memory in Win32k can be exploited locally via a specially crafted application to gain privileges;
8. Improper handling of objects in memory in HID Parser Library driver can be exploited locally via a specially crafted application to gain privileges;
9. Memory corruption vulnerability in Windows GDI can be exploited locally via a specially crafted application to gain sensitive information;
10. Multiple vulnerabilities in Windows kernel can be exploited locally via a specially crafted application to gain privileges or obtain sensitive information;
11. An incorrect access checking in NTFS can be exploited locally via a specially crafted application to gain privileges;
12. Improper handling of objects in memory in Http.sysr can be exploited locally via a specially crafted request to execute arbitrary code;
13. Improper handling of objects in memory in Windows Media Foundation can be exploited locally via a specially designed document to execute arbitrary code;
14. An incorrect permissions enforcing in Windows Kernel API can be exploited locally via a specially crafted application to gain privileges;
15. Improper virtual registry management in Desktop Bridge can be exploited locally via a specially crafted application to gain privileges;
