MS14-056 Cumulative Security Update for Internet Explorer (2987107)

Published Date: October 14, 2014

Version: 1.0

General Information

Executive Summary

This security update resolves fourteen privately reported vulnerabilities in 
Internet Explorer. The most severe of these vulnerabilities could allow remote
code execution if a user views a specially crafted webpage using Internet 
Explorer. An attacker who successfully exploited these vulnerabilities could 
gain the same user rights as the current user. Customers whose accounts are 
configured to have fewer user rights on the system could be less impacted than
those who operate with administrative user rights.

This security update is rated Critical for Internet Explorer 6 (IE 6), 
Internet Explorer 7 (IE 7), Internet Explorer 8 (IE 8), Internet Explorer 9 
(IE 9), Internet Explorer 10 (IE 10), and Internet Explorer 11 (IE 11) on 
affected Windows clients, and Moderate for Internet Explorer 6 (IE 6), 
Internet Explorer 7 (IE 7), Internet Explorer 8 (IE 8), Internet Explorer 9 
(IE 9), Internet Explorer 10 (IE 10), and Internet Explorer 11 (IE 11) on 
affected Windows servers. For more information, see the Affected Software 
section.

The security update addresses the vulnerabilities by modifying the way that 
Internet Explorer handles objects in memory, by adding additional permission 
validations to Internet Explorer, and by helping to ensure that affected 
versions of Internet Explorer properly implement the ASLR security feature.

Vulnerability Information

Multiple Elevation of Privilege Vulnerabilities in Internet Explorer

Elevation of privilege vulnerabilities exist within Internet Explorer. An 
attacker who successfully exploited these vulnerabilities could elevate 
privileges in affected versions of Internet Explorer. These vulnerabilities by
themselves do not allow arbitrary code to be run. However, these 
vulnerabilities could be used in conjunction with another vulnerability (e.g.,
a remote code execution vulnerability) that could take advantage of the 
elevated privileges when running arbitrary code.

Vulnerability title 					CVE number

Internet Explorer Elevation of Privilege Vulnerability 	CVE-2014-4123

Internet Explorer Elevation of Privilege Vulnerability 	CVE-2014-4124

Internet Explorer ASLR Bypass Vulnerability 		CVE-2014-4140

A security feature bypass vulnerability exists in Internet Explorer that could
allow an attacker to bypass the Address Space Layout Randomization (ASLR) 
security feature, which helps protect users from a broad class of 
vulnerabilities. The security feature bypass by itself does not allow 
arbitrary code execution. However, an attacker could use this ASLR bypass 
vulnerability in conjunction with another vulnerability, such as a remote code
execution vulnerability, that could take advantage of the ASLR bypass to run 
arbitrary code.

To view this vulnerability as a standard entry in the Common Vulnerabilities 
and Exposures list, see CVE-2014-4140.

Multiple Memory Corruption Vulnerabilities in Internet Explorer

Remote code execution vulnerabilities exist when Internet Explorer improperly
accesses objects in memory. These vulnerabilities could corrupt memory in such
a way that an attacker could execute arbitrary code in the context of the 
current user.
