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.

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: tac@cisco.com
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 "psirt@cisco.com" or "security-alert@cisco.com"
for software upgrades.
