MS16-023: Cumulative Security Update for Internet Explorer (3142015)
Bulletin Number: MS16-023
Bulletin Title: Cumulative Security Update for Internet Explorer
Severity: Critical
KB Article: 3142015
Version: 1.0
Published Date: March 8, 2016
Executive Summary
This security update resolves vulnerabilities in Internet Explorer. The most
severe of the vulnerabilities could allow remote code execution if a user
views a specially crafted webpage using Internet Explorer. An attacker who
successfully exploited this vulnerability could gain the same user rights as
the current user. If the current user is logged on with administrative user
rights, 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.
This security update is rated Critical for Internet Explorer 9 (IE 9), and
Internet Explorer 11 (IE 11) on affected Windows clients, and Moderate for
Internet Explorer 9 (IE 9), Internet Explorer 10 (IE 10), and Internet
Explorer 11 (IE 11) on affected Windows servers.

Vulnerability Information
Multiple Internet Explorer Memory Corruption Vulnerabilities
Multiple 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.
An attacker could host a specially crafted website that is designed to exploit
these vulnerabilities through Internet Explorer, and then convince a user to
view the website. The attacker could also take advantage of compromised
websites and websites that accept or host user-provided content or
advertisements by adding specially crafted content that could exploit the
vulnerabilities. In all cases, however, an attacker would have no way to force
users to view the attacker-controlled content. Instead, an attacker would have
to convince users to take action, typically by way of enticement in an email
or Instant Messenger message, or by getting them to open an attachment sent
through email.
An attacker who successfully exploited these vulnerabilities could gain the
same user rights as the current user. If the current user is logged on with
administrative user rights, an attacker who successfully exploited these
vulnerabilities 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. The update addresses the vulnerabilities by modifying
how Internet Explorer handles objects in memory.
