Section II: Security Alert Summary
2. Microsoft Security Bulletins
2.1 MS02-015 28 March 2002 Cumulative Patch for Internet Explorer
- released 28 March 2002
- revised 8 April 2002
Risk: ****CRITICAL
- Internet systems: CRITICAL
- Intranet systems: CRITICAL
- Client systems: CRITICAL
Impact: Run code of attacker's choice
Systems Affected:
- Internet Explorer 6.0
- Internet Explorer 5.5
- Internet Explorer 5.01
- Previous versions are no longer supported, were not tested, and
may or may not be vulnerable. Note that Microsoft ONLY supports IE
5.01 at SP2 or higher, and ONLY on NT 4.0 and Windows 2000.
Summary:
Microsoft has released a patch intended to address all known
vulnerabilities in Internet Explorer to date, with the exception of
the VBScript vulnerability addressed in MS00-009 (a separate patch is
available for that vulnerability). In addition, this patch addresses
two new vulnerabilities:
1. Cookie-based script execution. Andreas Sandblad discovered a
vulnerability in the way that IE handles HTML scripts embedded in
cookies. Under normal conditions, scripts should be executed in the
Security Zone of the originating web site (normally the Internet Zone).
Embedding an HTML script in a cookie will cause the script to be
saved to the user's hard drive, such that when the web site opens the
cookie, the script will execute in the Local Computer Zone instead,
with the privileges of the logged-in user. (NOTE: IE 5.01 SP2 is NOT
vulnerable to this issue.)
2. Local executable invocation via object tag. The CODEBASE
HTML tag is used to specify a location for downloading "helper"
applications for displaying web content where those applications may
not be present on the user's system. A flaw in the way IE handles
the CODEBASE tag causes programs invoked using the tag to be run in
the Local Computer Zone instead of the Zone of the originating site
(normally the Internet Zone). As a result, an attacker could use a
malicious web site or HTML email to run an executable located on the
victim's machine. The attacker would need to know the location of
the executable, and would not be able to pass any parameters to the
program. Users running Outlook 2002, Outlook Express 6, or Outlook
98 or 2000 with the email security patch installed are protected from
the email-borne version of this exploit.

2.2 MS02-018 Cumulative Patch for Internet Information Services
(Q319733)
- released 10 April 2002
- revised 11 April 2002
- revised 12 April 2002
Risk: ****CRITICAL
- Internet systems: CRITICAL
- Intranet systems: CRITICAL
- Client systems: MODERATE
Impact: Run code of attacker's choice
Systems Affected:
- - Internet Information Server (IIS) 4.0
- - Internet Information Server (IIS) 5.0
- - Internet Information Server (IIS) 5.1 (ships with Windows XP
Professional)
- - Internet Information Server (IIS) 6.0 - this affects users running
the BETA version of .NET Server PRIOR to Build 3605.
- - Previous versions are no longer supported, were not tested, and
may or may not be vulnerable.
Summary:
Microsoft has released a patch intended to address all known
vulnerabilities in Internet Information Server (IIS) to date, including
several non-security fixes described in Q319733. In addition, this
patch addresses ten new security vulnerabilities. (NOTE: The patch
does NOT address four IIS 4.0 vulnerabilities that must be corrected
by "administrative action," nor does it address vulnerabilities
in add-on products such as Front Page Extensions or Index Server.
See MS02-018 for details.)
1. Buffer overrun in Chunked Encoding mechanism. The HTTP
specification allows clients to transmit large amounts of data to a web
server by encoding them in "chunks" of a size defined by the client.
eEye Digital Security discovered an arithmetic error in the ISAPI
extension that handles chunks via Active Server Pages causes IIS
to miscalculate the size of the buffer needed to handle the chunk.
This creates a buffer overrun condition where an attacker could cause
the IIS service to crash, or possible execute code in the context of
the IIS server (by default, SYSTEM on IIS 4.0 and IWAM_machinename on
IIS 5.0). IIS 5.1 is NOT affected by this vulnerability. Users who
have configured IIS to serve static pages only (i.e., by using the
IISLockdown tool) are also not affected. This attack could be blocked
by using Microsoft's URLScan tool.
2. Microsoft-discovered variant of Chunked Encoding buffer overrun.
This vulnerability is similar to the preceding one, but it affects all
versions of IIS (4.0, 5.0, and 5.1) and cannot be blocked by URLScan.
Microsoft did not release any additional details on this vulnerability.
3. Buffer overrun in HTTP header handling. When a client sends a
request to a web server, it includes various parameters in the HTTP
headers. Each header is bounded by delimiting characters, and IIS
normally checks for the existence of those characters to determine
that they are present and that each header is an appropriate length.
Serge Mister of Entrust discovered a vulnerability where it is
possible to spoof the normal checking that IIS performs so that IIS
would consider the headers valid when they were not. An attacker
could exploit this to send excess data to the server within the HTTP
headers, resulting in a buffer overrun that could crash the IIS service
or possibly run code in the context of the IIS server (SYSTEM on IIS
4.0, IWAM_machinename on IIS 5.0/5.1). Users who have configured
IIS to serve static pages only (i.e., using the IISLockdown tool) are
not vulnerable. URLScan can also be used to block this type of attack.
4. Buffer overrun in ASP Server-Side Include function. Microsoft has
discovered a flaw in the way that IIS handles file name requests as
part of Active Server Pages using Server-Side includes. An attacker
could craft a URL that requested an overly long, invalid file name.
When processed as part of a server-side include the file name length
is not checked before it is parsed, allowing an attacker to disrupt
the IIS service or possibly run code in the context of the IIS server
(SYSTEM on IIS 4.0, IWAM_machinename on IIS 5.0/5.1). Users who have
configured IIS to serve static pages only (i.e., using the IISLockdown
tool) are not vulnerable. URLScan can also be used to block this
type of attack.
5. Buffer overrun in HTR ISAPI extension. Dave Aitel of
Stake
and Peter Grundl of KPMG have discovered a vulnerability in the way
that the HTR ISAPI extension calculates the buffer required to handle
requests. Due to the miscalculation, an attacker could send a series
of malformed requests to the server and take advantage of this buffer
overrun condition to crash the IIS server or possibly run code in the
context of the IIS server (SYSTEM on IIS 4.0, IWAM_machinename on IIS
5.0). IIS 5.1 is NOT affected by this vulnerability. HTR extensions
are used primarily to enable web-based password management; Microsoft
recommends that they be disabled.
6. Access violation in URL error handling. Dave Aitel of
Stake has
discovered a flaw in the way IIS handles particular error conditions.
When one of the ISAPI filters installed with Front Page Server
Extensions or Microsoft ASP.NET receives a request for a URL that is
too long, IIS mishandles the error, resulting in an access violation
that will crash the IIS service and cause a denial of service.
7. Denial of service via FTP status request. A flaw in the way that
IIS processes requests for the status of an FTP connection would allow
an attacker to crash the FTP service by sending a specially malformed
request to the server. Because FTP services are provided by IIS,
the attacker could crash the IIS service via this attack as well.
8. - 10. Three cross-site scripting vulnerabilities (in the IIS Help
File search facility, in HTTP error pages, and in the IIS redirect
response message). IIS 4.0 is NOT affected by the vulnerability
in the IIS Help File search facility. Cross-site scripting
vulnerabilities in various IIS components could allow an attacker
to create a malicious web site that would run a script in the user's
browser in the context of a third-party web site. The script would
be able to access information in any cookies from the third-party
site, and might also be able to take other action on the user's
machine, depending on the security context of the third-party site.
These vulnerabilities were discovered by Joe Smith and zenomorph,
Thor Larholm, and Keigo Yamazaki, respectively.

2.3 MS02-019 Unchecked Buffer in Internet Explorer and Office for
Mac Can Cause Code to Execute (Q321309)
- released 16 April 2002
Risk: ****CRITICAL
- Internet systems: NONE
- Intranet systems: NONE
- Client systems: CRITICAL
Impact: Run code of attacker's choice
Systems Affected:
- Internet Explorer 5.1 for Macintosh OS 8, 9, and X
- Outlook Express 5.0 - 5.0.3 for Macintosh
- Microsoft Entourage 2001 and X for Macintosh
- Microsoft PowerPoint 98, 2001, and X for Macintosh
- Microsoft Excel 2001 and X for Macintosh
- Previous versions are no longer supported, were not tested, and
may or may not be vulnerable.
Summary:
Microsoft has released a patch intended to address all known
vulnerabilities in Internet Explorer 5.1 for Macintosh and Office
98, 2001 and X for Macintosh. In addition, this patch addresses two
new vulnerabilities:
1. Unchecked buffer in HTML element. A buffer overflow exists in the
way that Internet Explorer and Office (which supports HTML) handle a
particular HTML element. An attacker could craft a malicious web page
or HTML email to exploit this buffer overflow, causing the application
to crash or possibly executing code of the attacker's choice on the
victim machine in the context of the currently logged-in user.
2. Local AppleScript invocation. A flaw in the way IE handles
HTML elements that invoke AppleScripts. An attacker could craft a
malicious web page or HTML email that invoked a local AppleScript via a
particular HTML element. Invoking the script in this way would cause
IE to execute the script in the (more restrictive) browser context,
allowing the attacker to bypass the stricter security checks that
would normally be run on a locally-executed script. The attacker
would have to know the full path and file name of the AppleScript.
This vulnerability only affects IE 5.1 for Mac OS 8 and 9.

2.4 MS02-016 Q318593: Opening Group Policy Files for Exclusive Read
Blocks Policy Application
- released 4 April 2002
- revised 8 April 2002
Risk: ** MODERATE
- Internet systems: LOW
- Intranet systems: MODERATE
- Client systems: NONE
Impact: Block application of Group Policy
Systems Affected:
- Windows 2000 Server, Advanced Server, and Datacenter Server
Summary:
A malicious user could open the files used to configure and apply
Group Policy for exclusive read access. Because the files are locked
by the exclusive read operation, Group Policy settings would not be
applied to subsequent user or computer logins, as long as the policy
files remained locked. An attacker would need to have a legitimate
user account in order to carry out this attack.

2.6 MS02-020 SQL Extended Procedure Functions Contain Unchecked Buffers
(Q319507)
- released 17 April 2002
Risk: ** MODERATE
- Internet systems: MODERATE
- Intranet systems: MODERATE
- Client systems: MODERATE
Impact: Run code of attacker's choice
Systems Affected:
- Microsoft SQL Server 7.0
- Microsoft SQL Server 2000
- Previous versions are no longer supported, have not been tested,
and may or may not be vulnerable.
Summary:
An extended stored procedure is an external routine written in a
programming language such as C. These procedures can be called and
executed by various SQL Server procedures. Several of the external
stored procedures included in SQL Server by default contain unchecked
buffers. An attacker who could call one of the affected procedures,
either locally of through a web page front end, could overrun the
buffer to crash the system or possibly execute code in the context
of the SQL Server (by default, SQL Server runs as a domain user).

Risk: ** MODERATE
- Internet systems: NONE
- Intranet systems: NONE
- Client systems: MODERATE
Impact: Run code of attacker's choice
Systems Affected:
- Microsoft Outlook 2000
- Microsoft Outlook 2002
- Previous versions are no longer supported, were not tested, and
may or may not be vulnerable.
Summary:
A flaw in the way Outlook 2000 and 2002 apply security settings could
allow an attacker to create a malicious HTML email containing a script
that would be executed in the context of the currently logged on
user if the user replied to or forwarded the message. When a user
reads an HTML email, the HTML is rendered using Internet Explorer
Security Zone settings that prevent script execution. However,
if a user replies to or forwards the message, and the user is using
Microsoft Word as their email editor, the HTML message is opened in
Word for editing and the script is allowed to run.

3. Additional Microsoft Software Issues
3.1 Internet Explorer Issues
3.1.1 Microsoft Internet Explorer History List Script Injection
Vulnerability ("Back Button" Vulnerability)
* Risk: MODERATE
* Impact: Run code in weaker security context
* Summary: Internet Explorer will store javascript: URLs in the
browser's History list. Javascript: URLs are normally executed in
the security zone of the last viewed page. However, a user could
navigate to a javascript: URL by calling it from the browser history
list (i.e., by clicking the "Back" button). This could result in the
script executing in the security zone of a different page, possibly
with more permissive security settings.

3.1.2 Microsoft Internet Explorer Dialog Same Origin Policy Bypass
Vulnerability
* Risk: MODERATE
* Impact: Run code in weaker security context
* Summary: Internet Explorer uses the showModalDialog and
showModelessDialog methods to display dialog boxes on web pages.
The dialogArguments property enforces security by ensuring that
the information displayed in the dialog box originates from the same
domain as the calling page. However, if the URL that calls the dialog
includes a redirect from the calling page to a secondary page, the
security checks are not performed on the secondary page. This could
allow an attacker to insert executable code from an untrusted site
into the dialog box.

4. Virus Alerts
4.1 New Klez Worm Variant
A new variant of the Klez worm (w32.klez) has been circulating in the
wild. The code for the new variant has been sufficiently modified that
it may elude anti-virus software patched against earlier versions of
the worm. The Klez worm arrives as an email with a random subject line
and randomly-named attachment. The worm uses a mass-emailing routine
to propagate, copies itself to local and mapped drives, and attempts
to disable common anti-virus software. During the mass-mailing
process, the worm randomly attaches a file from the local system to
the outbound message, possibly releasing confidential information.
Finally, the worm drops a copy of the Elkern virus (w32.elkern)
for execution, which may crash the computer or destroy all files on
local hard drives based on a date trigger. The virus attempts to
take advantage of the vulnerability described in Microsoft security
bulletin MS01-020, and may execute automatically on systems running
unpatched versions of Internet Explorer.
