Background

Cisco evaluates Microsoft security notices and updates for potential impact to Cisco Contact Center products.

The qualification process results in one of four categorical ratings being applied to a given update: Impacting, Not Impacting, Deferred, or Not Applicable.

The four ratings are defined in the Cisco Customer Contact Software Policy for use of Third-Party Software and Security Updates document.

For the security updates listed in Problem Description section of this bulletin, Cisco has assigned the updates to the following categories:

Impacting

MS05-050 - Vulnerability in DirectShow Could Allow Remote Code Execution

MS05-055 - Vulnerability in Windows Kernel Could Allow Elevation of Privilege

Deferred

MS05-054 - Cumulative Security Update for Internet Explorer

While an attacker who successfully exploited these vulnerabilities could take complete control of an affected system, Production Contact Center application servers should not be used for chat, e-mail or to browse unknown and potentially dangerous Web or FTP sites. Furthermore, proper measures should be implemented to restrict and audit local and remote user access to application servers.

Proper care should be taken in deciding on which updates to apply to your systems. For additional information on the security measures to be considered in an ICM environment, refer to the Security Best Practices for Cisco Intelligent Contact Management Software Guide.

Product	Version(s)	Tested (Y/I*)	Components Tested (All or Specific)
ICM/IPCC	7.0(0) SR2	Y	All
ICM/IPCC	6.0 SR4	Y	All
ICM/IPCC	5.0 SR12	Y	All
CVP	3.0 SR1	Y	All

*"I" indicates that testing is in progress and will be updated when complete.

Customers should follow Microsoft's guidelines regarding when and how they should apply these updates. Refer to the Microsoft Security Homepage for full details of the potential exposure from the caveat.

Problem Symptoms

It is important to point out that Cisco Contact Center Support has not had any cases pertaining to this vulnerability recorded from our customer base as of December 14, 2005.

Workaround/Solution

Cisco has assessed, and where deemed appropriate, validated the Microsoft security patches addressed in this bulletin. Deferred security updates will be folded in to regression testing of the listed products' next service release or major release, whichever comes first.

Cisco recommends that Contact Center customers separately assess all security patches released by Microsoft and install those deemed appropriate for their environments.

Cisco will continue to provide a service of separately assessing and where necessary, validating higher severity security patches that may be relevant to the Contact Center Enterprise software products.

Visit the Microsoft website to acquire the fixes. Keep in mind that you should download the appropriate fixes based on the version of the Microsoft operating system deployed in your environment and service pack level.
