Issue:
=====
This is a cumulative patch that includes the functionality of all
previously released patches for Internet Explorer 5.01, 5.5 and
6.0. In addition, it eliminates the following newly discovered
vulnerabilities:
- A vulnerability involving the cross-domain security model of
Internet Explorer, which keeps windows of different domains from
sharing information. This flaw could result in the execution of
script in the My Computer zone. To exploit this flaw, an attacker
would have to host a malicious Web site that contained a Web page
designed to exploit this particular vulnerability and then
persuade a user to visit that site. After the user has visited
the malicious Web site, it would be possible for the attacker to
run malicious script by misusing the method Internet Explorer
uses to retrieve files from the browser cache, and cause that
script to access information in a different domain. In the worst
case, this could enable the Web site operator to load malicious
script code onto a user's system in the security context of the
My Computer zone. In addition, this flaw could also enable an
attacker to run an executable file that was already present on
the local system or view files on the computer. The flaw exists
because a file from the Internet or intranet with a maliciously
constructed URL can appear in the browser cache running in the My
Computer zone.
- A vulnerability that occurs because Internet Explorer does not
properly determine an object type returned from a Web server. It
could be possible for an attacker who exploited this
vulnerability to run arbitrary code on a user's system. If a user
visited an attacker's Web site, it would be possible for the
attacker to exploit this vulnerability without any other user
action. An attacker could also craft an HTML-based e-mail that
would attempt to exploit this vulnerability.
This patch also sets the Kill Bit on the BR549.DLL ActiveX
control. This control implemented support for the Windows
Reporting Tool, which is no longer supported by Internet
Explorer. The control has been found to contain a security
vulnerability. To protect customers who have this control
installed, the patch prevents the control from running or from
being reintroduced onto users' systems by setting the Kill Bit
for this control. This issue is discussed further in Microsoft
Knowledge Base article 822925.
In addition to these vulnerabilities, a change has been made to
the way Internet Explorer renders HTML files. This change
addresses a flaw in the way Internet Explorer renders Web pages
that could cause the browser or Outlook Express to fail. Internet
Explorer does not properly render an input type tag. A user
visiting an attacker's Web site could allow the attacker to
exploit the vulnerability by viewing the site. In addition, an
attacker could craft a specially formed HTML-based e-mail that
could cause Outlook Express to fail when the e-mail was opened or
previewed.
