       (contributed by Mark Joseph Edwards, News Editor,

    * MICROSOFT .NET PASSPORT MUST SET SECURITY BAR HIGHER

    Although in the past Microsoft lambasted open-source projects as
    inherently insecure, the company has chosen to embrace the idea of
    open source by using the Kerberos protocol--again. According to
    vnunet.com (see the URL below), Microsoft will marry its technology
    with Kerberos technology to make its next generation of .NET Passport
    more secure and somewhat open-source.
       http://www.vnunet.com/news/1125551

    The last time Microsoft began to use Kerberos technology, in
    conjunction Windows 2000, critics screamed because Microsoft had
    apparently inserted undocumented modifications into the technology.
    Twisting open-source code into proprietary technology through
    undocumented changes is a definite no-no. Now, however, Microsoft is
    turning to Kerberos to improve .NET Passport security in response to
    the Federal Trade Commission (FTC) scrutiny that resulted in specific
    charges.
       http://www.microsoft.com/netservices/passport

    Microsoft described its .NET Passport, launched in 1999, as "a suite
    of Web-based services that makes using the Internet and purchasing
    online easier and faster. .NET Passport provides users with single
    sign-in (SSI) and fast purchasing capability at a growing number of
    participating sites, reducing the amount of information users must
    remember or retype." Many popular shopping sites, including eBay
    (which recently acquired PayPal), offer .NET Passport as a means to
    conduct business through their portals.
       http://www.microsoft.com/netservices/passport/overview.asp

    Because SSI is the core feature of .NET Passport, Kerberos is an
    obvious choice to use as part of the core methodology of
    authentication. To learn more about Microsoft's Kerberos
    implementation, read Jan De Clerq's article "Win.NET Server Kerberos"
    on our Web site (see the URL below). De Clerq discusses the new
    Kerberos delegation features that Microsoft has embedded in Windows
    .NET Server (Win.NET Server) 2003.
       http://www.secadministrator.com/articles/index.cfm?articleid=26450

    According to the FTC, Microsoft made false claims about .NET
    Passport's security and privacy. Microsoft recently came to an
    agreement with the commission (see the URL below) by which the company
    will work to mend the problems. Under the agreement, Microsoft will
    change the way the company communicates with consumers about the
    security and privacy of the .NET Passport service and change the way
    Kids Passport works to some extent, as you'll see below.
       http://www.ftc.gov/opa/2002/08/microsoft.htm

    As Microsoft Senior Vice President and General Counsel Brad Smith
    noted, "The FTC's complaint asserts that we should have taken
    additional security steps earlier in the operation of the Passport
    service." Smith went on to say: "Even though we know of no instance
    where a Passport user's information has ever been compromised, in
    hindsight we wish we had held ourselves to an even higher bar."

    The FTC's complaints were certainly justified, however. You might
    recall that in November 2001, I wrote about one researcher who
    required just 30 minutes to discover that when Hotmail and .NET
    Passport were combined, an intruder could quickly empty a user's
    "wallet." On Microsoft's behalf, Smith acknowledged .NET Passport's
    shortcomings and promised change: "Consistent with our heightened
    security obligations, we accept responsibility for the past and will
    focus on living up to this high level of responsibility in the
    future."
       http://www.secadministrator.com/articles/index.cfm?articleid=23161

    Toward that goal, according to Microsoft Corporate Vice President
    Brian Arbogast, the company will "document the comprehensive
    information security program that protects the security,
    confidentiality, and integrity of the personal information collected
    from our customers. We will also ensure that a third-party
    professional firm reviews, advises us, and ultimately certifies that
    our information-security program is designed and operates with
    sufficient effectiveness to provide reasonable assurances that the
    security, confidentiality, and integrity of every Passport user's
    information is protected. We will also ensure that all of the
    statements we make about the service are accurate and clear. Finally,
    we will strengthen training for all the managers involved with
    Passport, to ensure that they understand and comply fully with this
    order."

    The FTC also raised concerns about Kids Passport, particularly noting
    that children could bypass the controls their parents placed on the
    technology. Microsoft said that it has taken steps to remedy that
    situation by making Kids Passport more "kid-proof."

    The new agreement with the FTC will be in force for 20 years. To read
    more about Microsoft's perspective on the agreement, visit the Web
    site at the URL below. In related news, Microsoft has licensed
    security technology from RSA Security that will strengthen the
    authentication mechanisms .NET Passport uses. Be sure to read about
    that licensing agreement in the related news item in this newsletter.

    2. ==== SECURITY RISKS ====
       (contributed by Ken Pfeil, kenwinnetmag.com)

    * DoS IN ORACLE 9I APPLICATION SERVER FOR WINDOWS
       stake discovered a Denial of Service (DoS) condition in Oracle 9i
    Application Server's Web Cache Manager Tool. An attacker who sends a
    specially formatted HTTP GET request to the port on which the Web
    Cache Administration process is listening can crash the administration
    process. The vendor, Oracle, has released Oracle Security Alert #43 to
    address this vulnerability but hasn't released a patch. The company
    will include a fix for this vulnerability in Oracle 9i Application
    Server 9.02.
       http://www.secadministrator.com/articles/index.cfm?articleid=26941

    * MULTIPLE VULNERABILITIES IN MICROSOFT SERVICES FOR UNIX 3.0
       Three new vulnerabilities exist in the Windows Help Facility, one
    of which could let an attacker execute arbitrary code on the
    vulnerable system. These new vulnerabilities consist of an integer
    overflow in the XML Data Reduced (XDR) library, a buffer overrun in
    remote procedure calls (RPCs), and an RPC implementation error. The
    vendor, Microsoft, has released Security Bulletin MS02-057 (Flaw in
    Services for Unix 3.0 Interix SDK Could Allow Code Execution) to
    address these vulnerabilities and recommends that affected users
    immediately apply the patch mentioned in the bulletin.
       http://www.secadministrator.com/articles/index.cfm?articleid=26889

    * BEARSHARE FILE-SHARING DIRECTORY TRAVERSAL VULNERABILITY
       A directory traversal vulnerability exists in the file-sharing
    program BearShare. This vulnerability stems from a flaw in the
    personal Web server portion of BearShare that could let an attacker
    view any file on the vulnerable system by issuing a specially crafted
    HTTP request. The vendor, Free Peers, has released version 4.0.6 to
    address the traversal issue described above, but the software is still
    vulnerable if an attacker uses certain HTTP requests, which the
    article lists. Free Peers hasn't yet addressed this second variant of
    the same problem.
       http://www.secadministrator.com/articles/index.cfm?articleid=26890

    * MULTIPLE VULNERABILITIES IN MICROSOFT SQL SERVER, MSDE 2000, AND
    MSDE 1.0
       Three new vulnerabilities exist in Microsoft SQL Server, Microsoft
    SQL Server Desktop Engine (MSDE) 2000, and Microsoft Data Engine
    (MSDE) 1.0, the most serious of which could let an attacker execute
    arbitrary code on the vulnerable system. The vulnerabilities are a
    buffer overrun in a section of code in SQL Server 2000 and MSDE 2000
    associated with user authentication, a buffer-overrun vulnerability
    that occurs in one of the Database Console Commands shipped as part of
    SQL Server 2000 and SQL Server 7.0, and a vulnerability associated
    with SQL Server 2000 and SQL Server 7.0 scheduled jobs. The vendor,
    Microsoft, has released Security Bulletin MS02-056 (Cumulative Patch
    for SQL Server) to address these vulnerabilities and recommends that
    affected users immediately apply the appropriate patch mentioned in
    the bulletin.

    * FAQ: HOW CAN I CONFIGURE THE GRACE PERIOD THAT WINDOWS USES FOR
    PASSWORD-PROTECTED SCREEN SAVERS?
       ( contributed by John Savill, http://www.windows2000faq.com )

    A. By default, when you activate a password-protected screen saver,
    Windows provides a brief grace period during which keyboard and mouse
    activity will stop the screen saver and let you access the system
    without having to enter the password. To modify this grace period,
    perform the following steps:
       1. Start a registry editor (e.g., regedit.exe).
       2. Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
    NT\CurrentVersion\Winlogon registry subkey.
       3. From the Edit menu, select New, DWORD Value.
       4. Enter a name of ScreenSaverGracePeriod, then press Enter.
       5. Double-click the new value, set the "Value data" to the number
    of seconds (from 0 to 2,147,483) that you want to use for the grace
    period, set the Base type to decimal, then click OK.
       6. Restart the machine for the change to take effect.
