An information disclosure vulnerability exists when Windows Update Client fails to properly handle objects in memory, aka 'Windows Update Client Information Disclosure Vulnerability'.

The remote Windows host is missing security update 4519338.
It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in the way     that the Chakra scripting engine handles objects in     memory in Microsoft Edge (HTML-based). The vulnerability     could corrupt memory in such a way that an attacker     could execute arbitrary code in the context of the     current user. An attacker who successfully exploited the     vulnerability could gain the same user rights as the     current user. (CVE-2019-1307, CVE-2019-1308,     CVE-2019-1335)

An attacker who successfully     exploited this vulnerability could gain the ability to     downgrade NTLM security features.  (CVE-2019-1166)

  - An elevation of privilege vulnerability exists in the     Windows redirected drive buffering system (rdbss.sys)     when the operating system improperly handles specific     local calls within Windows 7 for 32-bit systems. When     this vulnerability is exploited within other versions of     Windows it can cause a denial of service, but not an     elevation of privilege.  (CVE-2019-1325)

  - An elevation of privilege vulnerability exists when     Windows Error Reporting manager improperly handles hard     links. An attacker who successfully exploited this     vulnerability could overwrite a targeted file leading to     an elevated status.  (CVE-2019-1315, CVE-2019-1339)

  - A spoofing vulnerability exists when Microsoft Browsers     improperly handle browser cookies. An attacker who     successfully exploited this vulnerability could trick a     browser into overwriting a secure cookie with an     insecure cookie. The insecure cookie could serve as a     pivot to chain an attack with other vulnerabilities in     web services.  (CVE-2019-1357)

  - An elevation of privilege vulnerability exists when     Windows CloudStore improperly handles file Discretionary     Access Control List (DACL). An attacker who successfully     exploited this vulnerability could overwrite a targeted     file leading to an elevated status.  (CVE-2019-1321)

  - A remote code execution vulnerability exists when the     Microsoft XML Core Services MSXML parser processes user     input. An attacker who successfully exploited the     vulnerability could run malicious code remotely to take     control of the users system.  (CVE-2019-1060)
