An information disclosure vulnerability exists in the way that Microsoft Graphics Components handle objects in memory, aka "Microsoft Graphics Components Information Disclosure Vulnerability." This affects Microsoft Office, Microsoft Office Word Viewer, Office 365 ProPlus, Windows Server 2008, Microsoft PowerPoint Viewer, Microsoft Excel Viewer.

The Microsoft Office Viewer Products are missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in     Microsoft PowerPoint software when the software fails to     properly handle objects in Protected View. An attacker     who successfully exploited the vulnerability could run     arbitrary code in the context of the current user. If     the current user is logged on with administrative user     rights, an attacker 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-2018-8501)

  - A remote code execution vulnerability exists in the way     that Microsoft Graphics Components handle objects in     memory. An attacker who successfully exploited the     vulnerability could execute arbitrary code on a target     system.  (CVE-2018-8432)

  - An information disclosure vulnerability exists in the     way that Microsoft Graphics Components handle objects in     memory. An attacker who successfully exploited the     vulnerability could obtain information that could be     useful for further exploitation.  (CVE-2018-8427)

The remote Windows host is missing security update 4463104 or cumulative update 4463097. It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists in the     way that the Windows Graphics Device Interface (GDI)     handles objects in memory, allowing an attacker to     retrieve information from a targeted system. By itself,     the information disclosure 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.  (CVE-2018-8472)

  - A security feature bypass vulnerability exists in DNS     Global Blocklist feature. An attacker who successfully     exploited this vulnerability could redirect traffic to     malicious DNS endpoints. The update addresses the     vulnerability by updating DNS Server Role record     additions to not bypass the Global Query Blocklist.
    (CVE-2018-8320)

  - 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-2018-8330)

  - A remote code execution vulnerability exists in the way     that Microsoft Graphics Components handle objects in     memory. An attacker who successfully exploited the     vulnerability could execute arbitrary code on a target     system.  (CVE-2018-8432)

  - An information disclosure vulnerability exists when     DirectX improperly handles objects in memory. An     attacker who successfully exploited this vulnerability     could obtain information to further compromise the users     system. An authenticated attacker could exploit this     vulnerability by running a specially crafted     application. The update addresses the vulnerability by     correcting how DirectX handles objects in memory.
    (CVE-2018-8486)

  - An information disclosure vulnerability exists in the     way that Microsoft Graphics Components handle objects in     memory. An attacker who successfully exploited the     vulnerability could obtain information that could be     useful for further exploitation.  (CVE-2018-8427)

  - A remote code execution vulnerability exists when     Windows Hyper-V on a host server fails to properly     validate input from an authenticated user on a guest     operating system.  (CVE-2018-8489)

  - An elevation of privilege vulnerability exists when NTFS     improperly checks access. An attacker who successfully     exploited this vulnerability could run processes in an     elevated context.  (CVE-2018-8411)

  - An information disclosure vulnerability exists when     Windows Media Player improperly discloses file     information. Successful exploitation of the     vulnerability could allow an attacker to determine the     presence of files on disk.  (CVE-2018-8481,     CVE-2018-8482)

  - 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-2018-8494)

  - An elevation of privilege vulnerability exists in     Windows when the Win32k component fails to properly     handle objects in memory. An attacker who successfully     exploited this vulnerability could run arbitrary code in     kernel mode. An attacker could then install programs;
    view, change, or delete data; or create new accounts     with full user rights.  (CVE-2018-8453)

  - A remote code execution vulnerability exists in the     Microsoft JET Database Engine. An attacker who     successfully exploited this vulnerability could take     control of an affected system. An attacker could then     install programs; view, change, or delete data; or     create new accounts with full user rights. Users whose     accounts are configured to have fewer user rights on the     system could be less impacted than users who operate     with administrative user rights.  (CVE-2018-8423)

  - An Elevation of Privilege vulnerability exists in Filter     Manager when it improperly handles objects in memory. An     attacker who successfully exploited this vulnerability     could execute elevated code and take control of an     affected system. An attacker could then install     programs; view, change, or delete data; or create new     accounts with full user rights.  (CVE-2018-8333)
