    Summary
    =======
    
    This advisory describes vulnerabilities that affect Cisco products and
    applications that are installed on Microsoft operating systems incorporating
    the use of the Server Message Block (SMB) file sharing protocol. It is based on
    the vulnerabilities in Microsoft's SMB protocol, not due to a defect of the
    Cisco product or application.
    
    Vulnerabilities were discovered that enable an attacker to execute arbitrary
    code or perform a denial of service against the server. These vulnerabilities
    were discovered and publicly announced by Microsoft in their Microsoft Security
    Bulletin MS02-045.
    
    All Cisco products and applications that are using the Microsoft operating
    systems identified by Microsoft in their Microsoft Security Bulletin MS02-045 
    are considered vulnerable.
    
    This advisory is available at 
    http://www.cisco.com/warp/public/707/Microsoft-SMB-vulnerabilities-MS02-045-pub.shtml.

    All Other Products

    Obtaining Fixed Software
    ========================
    
    Where Cisco provides the operating system bundled with the product, Cisco is
    offering free software upgrades to address these vulnerabilities for all
    affected customers. Customers may only install and expect support for the
    feature sets they have purchased.
    
    Customers with service contracts should contact their regular update channels
    to obtain any software release containing the feature sets they have purchased.
    For most customers with service contracts, this means that upgrades should be
    obtained through the Software Center on Cisco's Worldwide Web site at 
    http://www.cisco.com/.
    
    Customers whose Cisco products are provided or maintained through a prior or
    existing agreement with third-party support organizations such as Cisco
    Partners, authorized resellers, or service providers should contact that
    support organization for assistance with obtaining the free software 
    upgrade(s).
    
    Customers who purchased directly from Cisco but who do not hold a Cisco service
    contract, and customers who purchase through third party vendors but are
    unsuccessful at obtaining fixed software through their point of sale, should
    obtain fixed software by contacting the Cisco Technical Assistance Center (TAC)
    using the contact information listed below. In these cases, customers are
    entitled to obtain an upgrade to a later version of the same release or as
    indicated by the applicable row in the Software Versions and Fixes table (noted
    above).
    
    Cisco TAC contacts are as follows:
    
      * +1 800 553 2447 (toll free from within North America)
      * +1 408 526 7209 (toll call from anywhere in the world)
      * e-mail: tacat_private
    
    See http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml for additional
    TAC contact information, including special localized telephone numbers and
    instructions and e-mail addresses for use in various languages.
    
    Please have your product serial number available and give the URL of this
    notice as evidence of your entitlement to a free upgrade.
    
    Please do not contact either "psirtat_private" or "security-alertat_private"
    for software upgrades.
    
    Workarounds
    ===========
    
    Microsoft documents several workarounds in their bulletin MS02-045.
