Microsoft Security Bulletin MS10-053 - Critical
Cumulative Security Update for Internet Explorer (2183461)
Version: 1.0
General Information
Executive Summary
This security update resolves six privately reported vulnerabilities in
Internet Explorer. The most severe vulnerabilities could allow remote code
execution if a user views a specially crafted Web page using Internet
Explorer. 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.
This security update is rated Critical for Internet Explorer 6, Internet
Explorer 7, and Internet Explorer 8. For more information, see the
subsection, Affected and Non-Affected Software, in this section.
The security update addresses the vulnerabilities by modifying the way that
Internet Explorer enforces security checks and handles objects in memory. For
more information about the vulnerabilities, see the Frequently Asked
Questions (FAQ) subsection for the specific vulnerability entry under the
next section, Vulnerability Information.

Vulnerability Information
Event Handler Cross-Domain Vulnerability - CVE-2010-1258
An information disclosure vulnerability exists in Internet Explorer that
could allow script to gain access to a browser window in another domain or
Internet Explorer zone. An attacker could exploit the vulnerability by
constructing a specially crafted Web page that could allow information
disclosure if a user viewed the Web page and then interacts with the browser
window using the mouse.
Uninitialized Memory Corruption Vulnerability - CVE-2010-2556
A remote code execution vulnerability exists in the way that Internet
Explorer accesses an object that has not been correctly initialized or has
been deleted. An attacker could exploit the vulnerability by constructing a
specially crafted Web page. When a user views the Web page, the
vulnerability could allow remote code execution. An attacker who
successfully exploited this vulnerability could gain the same user rights as
the logged-on user. If a user is logged on with administrative user rights,
an attacker who successfully exploited this vulnerability could take
complete control of an affected system. An attacker could then install
programs; view, change, or delete data; or create new accounts with full
user rights.
Uninitialized Memory Corruption Vulnerability - CVE-2010-2557
A remote code execution vulnerability exists in the way that Internet Explorer
accesses an object that has not been correctly initialized or has been
deleted. An attacker could exploit the vulnerability by constructing a
specially crafted Web page. When a user views the Web page, the vulnerability
could allow remote code execution. An attacker who successfully exploited
this vulnerability could gain the same user rights as the logged-on user. If
a user is logged on with administrative user rights, an attacker who
successfully exploited this vulnerability could take complete control of an
affected system. An attacker could then install programs; view, change, or
delete data; or create new accounts with full user rights.
Race Condition Memory Corruption Vulnerability - CVE-2010-2558
A remote code execution vulnerability exists in the way that Internet Explorer
accesses an object that may have been corrupted due to a race condition. An
attacker could exploit the vulnerability by constructing a specially crafted
Web page. When a user views the Web page, the vulnerability could allow remote
code execution. An attacker who successfully exploited this vulnerability
could gain the same user rights as the logged-on user. If a user is logged on
with administrative user rights, an attacker who successfully exploited this
vulnerability could take complete control of an affected system. An attacker
could then install programs; view, change, or delete data; or create new
accounts with full user rights.
Uninitialized Memory Corruption Vulnerability - CVE-2010-2559
A remote code execution vulnerability exists in the way that Internet Explorer
accesses an object that has not been correctly initialized or has been
deleted. An attacker could exploit the vulnerability by constructing a
specially crafted Web page. When a user views the Web page, the vulnerability
could allow remote code execution. An attacker who successfully exploited this
vulnerability could gain the same user rights as the logged-on user. If a user
is logged on with administrative user rights, an attacker who successfully
exploited this vulnerability could take complete control of an affected system.
An attacker could then install programs; view, change, or delete data; or
create new accounts with full user rights.
HTML Layout Memory Corruption Vulnerability - CVE-2010-2560
A remote code execution vulnerability exists in the way that Internet Explorer
accesses an object that has not been correctly initialized or has been deleted.
An attacker could exploit the vulnerability by constructing a specially
crafted Web page. When a user views the Web page, the vulnerability could
allow remote code execution. An attacker who successfully exploited this
vulnerability could gain the same user rights as the logged-on user. If a user
is logged on with administrative user rights, an attacker who successfully
exploited this vulnerability could take complete control of an affected system.
An attacker could then install programs; view, change, or delete data; or
create new accounts with full user rights.
