Rewterz Threat Advisory – Microsoft Windows Server 2019 Multiple Vulnerabilities

SEVERITY: HIGH

 

 

CATEGORY: VULNERABILITY

 

 

PUBLISH DATE: DECEMBER 17, 2018

 

 

ANALYSIS SUMMARY

 

Total 14 vulnerabilities have been detected in Microsoft Windows Server 2019.

These include the following errors:

 

  • An error related to Windows kernel when handling objects in memory can be exploited to cause information disclosure.
  • Remote Procedure Call Provider has a runtime error when initializing objects in memory, exploiting which, attackers can access certain confidential data.
  • Multiple errors related to the Windows GDI component when handling objects in memory can be exploited to disclose memory contents.
  • An error related to Windows kernel when handling objects in memory can be exploited to execute arbitrary code with kernel mode privileges. This flaw is being exploited in limited targeted attacks.
  • An error related to the Connected User Experiences and Telemetry service can be exploited to disrupt security feature functionality, bypassing some restrictions.
  • Using a specially crafted request, an attacker can execute arbitrary code with system privileges by exploiting an error related to DNS Server that will cause a heap-based overflow.
  • An error related to text-to-speech when handling objects in memory can be exploited to execute arbitrary code.
  • An error related to the Win32k component when handling objects in memory can be exploited to disclose uninitialized kernel memory and subsequently bypass KASLR.
  • An error related to DirectX when handling objects in memory can be exploited to disclose certain information.
  • An error related to the Win32k component when handling objects in memory can be exploited to execute arbitrary code with kernel mode privileges.
  • An error related to the kernel mode driver when handling objects in memory can be exploited to execute arbitrary code with kernel mode privileges.
  • An error when handling objects in memory can be exploited to cause the system to stop responding.
