Microsoft has issued a security bulletin containing patch KB2563894 for security advisory MS11-064. This security update resolves vulnerabilities in Microsoft Windows. The vulnerabilities could allow denial of service if an attacker sends a sequence of specially crafted Internet Control Message Protocol (ICMP) messages to a target system or sends a specially crafted URL request to a server that is serving Web content and has the URL-based Quality of Service (QoS) feature enabled. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2011-1871 and CVE-2011-1965 to these issues.
A description of the vulnerability may be found at:
Certain Avaya products utilize Microsoft Operating Systems and may be affected by this vulnerability.
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.
|Product:||Affected Version(s):||Risk Level:||Actions:|
|Avaya Aura® Conferencing Standard Edition||6.0.x||Low||Avaya recommends that customers install the security update as provided via Microsoft Windows Update.|
Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place, risk to Avaya products and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as the recommended update is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
When determining risk, Avaya takes into account many factors as outlined by Avaya's Security Vulnerability Classification Policy. The following table describes factors that mitigate the risk of specific vulnerabilities for affected Avaya products:
||This is a Low risk due to the Windows firewall enabled by default.|
||This is a Low risk due to the URL-based Quality of Service (QoS) feature not enabled by default.|
Avaya software-only products operate on general-purpose operating systems. Occasionally vulnerabilities may be discovered in the underlying operating system or applications that 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 the vulnerability directly but the underlying Microsoft Windows platform may be. For affected Microsoft Operating Systems, Microsoft recommends installing patches. Detailed instructions for patching the Operating System are given by Microsoft at the following link:
