1. Overview:

Microsoft issued a security bulletin summary for April 2006 which contained five security advisories: MS06-013, MS06-014, MS06-015, MS06-016, and MS06-017. The advisories describe vulnerabilities in various Microsoft Windows Operating Systems. A description of the vulnerabilities can be found at:

• http://www.microsoft.com/technet/security/bulletin/ms06-apr.mspx

2. Avaya Software-Only Products:

Avaya software-only products operate on general-purpose Operating Systems. Occasionally vulnerabilities may be discovered in the underlying Operating System or applications which come with the Operating System. These vulnerabilities often do not impact the software-only product directly but may threaten the integrity of the underlying platform.

In the case of this advisory Avaya software-only products are not affected by these vulnerabilities directly but the underlying Microsoft platform may be impacted. For affected Microsoft Operating Systems, Microsoft recommends installing patches. Detailed instructions for patching the Operating System are given by Microsoft at the following links:

• http://www.microsoft.com/technet/security/Bulletin/MS06-013.mspx
• http://www.microsoft.com/technet/security/Bulletin/MS06-014.mspx
• http://www.microsoft.com/technet/security/Bulletin/MS06-015.mspx
• http://www.microsoft.com/technet/security/Bulletin/MS06-016.mspx
• http://www.microsoft.com/technet/security/Bulletin/MS06-017.mspx

The following Avaya software-only products run on Microsoft Operating Systems and may have been installed on a vulnerable Microsoft Operating System. Customers should determine on which Microsoft Operating System the product was installed and then follow Microsoft's guidance for applying patches:

3. Avaya System Products

Avaya system products include an Operating System with the product when it is delivered. The system products described below are delivered with a Microsoft Operating System. Actions to be taken with these products are also described below.

4. Recommended Actions:

Avaya recommends that the Microsoft patches and/or workaround solutions are applied for the vulnerability outlined in the above system product table. Although certain Avaya system products utilize Microsoft Operating Systems and may be affected by these vulnerabilities, Avaya recommends that the use of e-mail clients and Internet browsers be restricted on Avaya system products (i.e. Outlook Express and Internet Explorer). The use of browsers should be restricted to authorized users-only as well as limited to the operational-needs of the product. Unrestricted access to the Intranet or Internet should be prohibited beyond the necessary functions of the product's web administration interface and to obtaining patches. This reduces the risk of vulnerabilities in these applications.

Further information regarding the Microsoft patches on Avaya system products is below:

MS06-013 Cumulative Security Update for Internet Explorer (912812): Several vulnerabilities has been discovered in Microsoft Internet Explorer running on Windows XP SP1 and SP2, Windows 2000 SP4, and Windows 2003 SP1. A remote attacker that could trick a user into visiting a malicious site could potentially take complete control of a system. The Avaya Modular Messaging Message Application Server, S8100, and UCC are affected by these vulnerabilities. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2006-1359, CVE-2006-1245, CVE-2006-1388, CVE-2006-1185, CVE-2006-1186, CVE-2006-1189, CVE-2006-1190, CVE-2006-1191 and CVE-2006-1192 to these issues.

MS06-014 Vulnerability in the Microsoft Data Access Components (MDAC) Function Could Allow Code Execution (911562) : A vulnerability has been reported Microsoft Data Access Components. A remote attacker that could trick a user into visiting a malicious site could potentially execute arbitrary code as user that is logged in. The Avaya Modular Messaging Messaging Application Server utilizes MDAC controls, and is therefore vulnerable. No other Avaya System Products utilize MDAC controls and are therefore not vulnerable. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-0003 to this issue.

MS06-015 Vulnerability in Windows Explorer Could Allow Remote Code Execution (908531): A vulnerability has been reported in Microsoft Windows Explorer. A remote attacker that could trick a user into visiting a malicious site could potentially take complete control of a system. The Avaya Modular Messaging Message Application Server, S8100, and Unified Communication Center are affected by these vulnerabilities. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-0012 to this issue.

MS06-016 Cumulative Security Update for Outlook Express (911567): A new vulnerability has been reported in Outlook Express. A remote attacker that exploited this vulnerability could potentially execute arbitrary code as a user that is logged in. Avaya system products do not utilize Outlook Express and are therefore not affected by this vulnerability. The Common Vulnerabilities and Exposures project (cve.mitre.org) had assigned the name CVE-2006-0014 to this issue.

MS06-017 Vulnerability in Microsoft Front Page Server Extensions Could Allow Cross Site Scripting (917627): A vulnerability has been reported in Microsoft Front Page Server Extensions on Microsoft Windows Server 2003 systems. An attacker that exploited this vulnerability could potentially execute arbitrary code as a user that is logged in. No Avaya System Products are currently available with Microsoft Windows Server 2003. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2006-0015 to this issue.
