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 perform a
denial of service against the server and may allow execution of arbitrary code.
These vulnerabilities were 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/cisco-sa-20020918-smb-dos.shtml.
This section provides details on affected products.
To determine if a product is vulnerable, review the list below. If the software versions or configuration information are provided, then only those combinations are vulnerable.
Other products in the list below may be installed on the affected Microsoft operating systems and should have the hotfix from Microsoft installed to remove the vulnerabilities. This list is not all inclusive, please refer to Microsoft's bulletin if you think you have an affected Microsoft platform.
No other Cisco products are currently known to be affected by these vulnerabilities.
The vulnerabilities have been described in more detail at
http://www.microsoft.com/technet/security/bulletin/MS02-045.asp
.
Successful exploitation of these vulnerabilities may cause the system to crash resulting in a loss of availability until the device has reinitialized.

.
Cisco has made free software available to address this vulnerability for affected customers. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment.
Customers may only install and expect support for the feature sets they have purchased. By installing, downloading, accessing or otherwise using such software upgrades, customers agree to be bound by the terms of Cisco's software license terms found at http://www.cisco.com/public/sw-license-agreement.html, or as otherwise set forth at Cisco.com Downloads at http://www.cisco.com/public/sw-center/sw-usingswc.shtml.
Do not contact either "psirt@cisco.com" or "security-alert@cisco.com" for software upgrades.
Customers with contracts should obtain upgraded software through their regular update channels. For most customers, this means that upgrades should be obtained through the Software Center on Cisco's worldwide website at http://www.cisco.com.
Customers whose Cisco products are provided or maintained through prior or existing agreement with third-party support organizations such as Cisco Partners, authorized resellers, or service providers should contact that support organization for guidance and assistance with the appropriate course of action in regards to this advisory.
The effectiveness of any workaround or fix is dependent on specific customer situations such as product mix, network topology, traffic behavior, and organizational mission. Due to the variety of affected products and releases, customers should consult with their service provider or support organization to ensure any applied workaround or fix is the most appropriate for use in the intended network before it is deployed.
Customers who purchase direct 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 get their upgrades by contacting the Cisco Technical Assistance Center (TAC). TAC contacts are as follows.
Have your product serial number available and give the URL of this notice as evidence of your entitlement to a free upgrade. Free upgrades for non-contract customers must be requested through the TAC.
Refer to 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.
The vulnerabilities described here have been discussed publicly on mailing lists and via security advisories released by other sources. Exploit code for these vulnerabilities is publicly available via the Internet.
