Cumulative Security Update for Microsoft Edge (MS17-007)

ITS Advisory Number: 
2017-022
Date(s) Issued: 
Tuesday, March 14, 2017
Subject: 
Cumulative Security Update for Microsoft Edge (MS17-007)
Overview: 

Multiple vulnerabilities have been discovered in Microsoft Edge, the most severe of which could allow remote code execution if a user views a specially crafted web page. Microsoft Edge replaced Internet Explorer as the default browser on Windows 10. Successful exploitation of the most severe of these vulnerabilities could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, 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 those who operate with administrative user rights.

 

Systems Affected: 
  • Microsoft Windows 10

  • Microsoft Windows Server 2016

Description: 

Multiple vulnerabilities have been discovered in Microsoft Edge, the most severe of which could allow for remote code execution if a user views a specially crafted web page. Details of these vulnerabilities are as follows:

  • Multiple remote code execution vulnerabilities exist in the way affected Microsoft scripting engines render when handling objects in memory. (CVE-2017-0010, CVE-2017-0015, CVE-2017-0032, CVE-2017-0035, CVE-2017-0067, CVE-2017-0070, CVE-2017-0071, CVE-2017-0094, CVE-2017-0131, CVE-2017-0132, CVE-2017-0133, CVE-2017-0134, CVE-2017-0136, CVE-2017-0137, CVE-2017-0138, CVE-2017-0141, CVE-2017-0150, CVE-2017-0151)
  • A remote code execution vulnerability exists when Microsoft Edge improperly accesses objects in memory. (CVE-2017-0037)
  • A remote code execution vulnerability exists when Microsoft Windows PDF Library improperly handles objects in memory. (CVE-2017-0023)
  • A remote code execution vulnerability exists when Microsoft Edge improperly accesses objects in memory. (CVE-2017-0034)
  • Multiple information disclosure vulnerabilities exist in the way that the affected components handle objects in memory. (CVE-2017-009, CVE-2017-0011, CVE-2017-0017, CVE-2017-0065, CVE-2017-0068)
  • Three spoofing vulnerabilities exist when a Microsoft browser does not properly parse HTTP responses. (CVE-2017-0012, CVE-2017-0033, CVE-2017-0069)
  • Three security feature bypass vulnerabilities exist when Microsoft Edge fails to correctly apply Same Origin Policy for HTML elements present in other browser windows. (CVE-2017-0066, CVE-2017-0135, CVE-2017-0140)

Successful exploitation of the most severe of these vulnerabilities could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, 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 those who operate with administrative user rights.

 

Actions: 
  • After appropriate testing, immediately install the updates provided by Microsoft.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to visit websites or follow links provided by unknown or untrusted sources.
  • Inform and educate users regarding the threats posed by hypertext links contained in emails or attachments especially from untrusted sources.  
  • Apply the Principle of Least Privilege to all systems and services.
