cumulative update.
Caveats: Microsoft Knowledge Base Article 883939 documents the currently
known issues that customers may experience when they install this
security update. The article also documents recommended solutions for
these issues. For more information, see Microsoft Knowledge Base Article
883939. This update does include hotfixes that have been released since
the release of MS04-004 or MS04-025, but they will only be installed on
systems that need them. Customers who have received hotfixes from
Microsoft or from their support providers since the release of MS04-004
or MS04-025 should review the 'I have received a hotfix from Microsoft
or my support provider since the release of MS04-004. Is that hotfix
included in this security update?' question in the FAQ section of this
bulletin to determine how you can make sure that the necessary hotfixes
are installed. Microsoft Knowledge Base Article 883939 also documents
this in more detail.

Technical Description:
----------------------
* PNG Image Rendering Memory Corruption Vulnerability - CAN-2005-1211 A
remote code execution vulnerability exists in Internet Explorer because
of the way that it handles PNG images. An attacker could exploit the
vulnerability by constructing a malicious PNG image that could
potentially allow remote code execution if a user visited a malicious
Web site or viewed a malicious e-mail message. An attacker who
successfully exploited this vulnerability could take complete control of
an affected system.
* XML Redirect Information Disclosure Vulnerability - CAN-2002-0648 An
information disclosure vulnerability exists in Internet Explorer because
of the way that it handles certain requests to display XML content. An
attacker could exploit the vulnerability by constructing a malicious Web
page that could potentially lead to information disclosure if a user
visited a malicious Web site or viewed a malicious e-mail message. An
attacker who successfully exploited this vulnerability could read XML
data from another Internet Explorer domain. However, user interaction is
required to exploit this vulnerability.

NTBugtraq Editor's Note:
Most viruses these days use spoofed email addresses. As such, using an
Anti-Virus product which automatically notifies the perceived sender of a
message it believes is infected may well cause more harm than good. Someone who
did not actually send you a virus may receive the notification and scramble
their support staff to find an infection which never existed in the first
place. Suggest such notifications be disabled by whomever is responsible for
your AV, or at least that the idea is considered.
