CVE Reference:   CVE-2017-11762, CVE-2017-11763, CVE-2017-11816, CVE-2017-11824, CVE-2017-8693   (Links to External Site)
Updated:  Oct 10 2017
Original Entry Date:  Oct 10 2017
Impact:   Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Root access via local system, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 7 SP1, 2008 R2 SP1, 2008 SP2, 2012, 2012 R2, 8.1, RT 8.1, 2016, 10, 10 Version 1511, 10 Version 1607, 10 Version 1703
Description:   Several vulnerabilities were reported in Microsoft Windows Graphics Component. A remote user can cause arbitrary code to be executed on the target user's system. A local user can obtain potentially sensitive information. A local user can gain system privileges on the target system.

A local user can run a specially crafted application to trigger an object memory handling error and obtain potentially sensitive information on the target system [CVE-2017-8693]. Versions 2016, 10, 10 Version 1511, 10 Version 1607, and 10 Version 1703 are affected.

A local user can run a specially crafted application to trigger an object memory handling error in the Windows Graphics Device Interface (GDI) and obtain potentially sensitive information on the target system [CVE-2017-11816].

A remote user can create content with specially crafted embedded fonts that, when loaded by the target user, will trigger a flaw in the Windows font library and execute arbitrary code on the target user's system [CVE-2017-11762, CVE-2017-11763].

A local user can run a specially crafted application to trigger an object memory handling error and run a process with elevated privileges on the target system [CVE-2017-11824].

Enrique Nissim of IOActive, Jaanus Kp of Clarified Security (via Trend Micro's Zero Day Initiative), and Wayne Low (@x9090) of Fortinet's FortiGuard Lab reported these vulnerabilities.

Impact:   A remote user can create content that, when loaded by the target user, will execute arbitrary code on the target user's system.

A local user can obtain potentially sensitive information on the target system.

A local user can obtain system privileges on the target system.

Solution:   The vendor has issued a fix.
