Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4577048 or cumulative update 4577038. It is, therefore, affected by multiple vulnerabilities :

- An elevation of privilege vulnerability exists when the Windows RSoP Service Application improperly handles memory. (CVE-2020-0648)

- An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly allows arbitrary writing to the file system. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2020-1030)

- A denial of service vulnerability exists in Windows DNS when it fails to properly handle queries. An attacker who successfully exploited this vulnerability could cause the DNS service to become nonresponsive.
(CVE-2020-0836, CVE-2020-1228)

- An information disclosure vulnerability exists in how splwow64.exe handles certain calls. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system (low- integrity to medium-integrity). This vulnerability by itself 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 (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted. The security update addresses the vulnerability by ensuring splwow64.exe properly handles these calls. (CVE-2020-0875)

An attacker who successfully exploited the vulnerability could take control of an affected system. There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit a malicious webpage. The security update addresses the vulnerability by correcting how Windows Media Audio Decoder handles objects. (CVE-2020-1508, CVE-2020-1593)

- A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Windows Jet Database Engine handles objects in memory. (CVE-2020-1039, CVE-2020-1074)

An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2020-1598)

- An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2020-1589)

- 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. (CVE-2020-1285)

- A denial of service vulnerability exists when Windows Routing Utilities improperly handles objects in memory.
An attacker who successfully exploited the vulnerability could cause a target system to stop responding.
(CVE-2020-1038)

- A local elevation of privilege vulnerability exists in how splwow64.exe handles certain calls. An attacker who successfully exploited the vulnerability could elevate privileges on an affected system from low-integrity to medium-integrity. This vulnerability by itself 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 (such as a remote code execution vulnerability or another elevation of privilege vulnerability) that is capable of leveraging the elevated privileges when code execution is attempted. The security update addresses the vulnerability by ensuring splwow64.exe properly handles these calls.. (CVE-2020-0790)

- An elevation of privilege vulnerability exists when the Windows Cryptographic Catalog Services improperly handle objects in memory. An attacker who successfully exploited this vulnerability could modify the cryptographic catalog. (CVE-2020-0782)

- A remote code execution vulnerability exists in the way that Microsoft Windows Codecs Library handles objects in 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. Exploitation of the vulnerability requires that a program process a specially crafted image file. The update addresses the vulnerability by correcting how Microsoft Windows Codecs Library handles objects in memory. (CVE-2020-1319)

- An information disclosure vulnerability exists in the way that the Windows Server DHCP service improperly discloses the contents of its memory. (CVE-2020-1031)
