2. Avaya System Products using a modified version of RHEL6 with affected packages installed:

For assessment and severity classification details refer to Section 3 of Avaya's Product Vulnerability Response Policy.
The "Resolution" column will be updated as fixes are made available. Please reference the "Information" column for any additional information regarding the affected product.

Recommended Actions for Products:
Avaya strongly recommends following 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 an Avaya provided product update or the recommended Avaya action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period, but the System Product operating system or application should not be modified unless the change is approved by Avaya. Making changes that are not approved may void the Avaya product service contract.

CVSS Scoring and Metrics:

Avaya uses the Common Vulnerability Scoring System (CVSS) base score and metrics as reported by the vendor for the affected component(s) or by the National Institute of Standards and Technology in the National Vulnerability Database. In some cases, such as where CVSS information is not available from the vendor or NIST, Avaya will calculate the CVSS base score and metrics. Customers are encouraged to calculate the Temporal and Environmental CVSS scores to determine how the vulnerability could affect their specific implementation or environment. For more information on CVSS and how the score is calculated, see Common Vulnerability Scoring System: Specification Document.

3. 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 that come with the operating system. These vulnerabilities may not impact the software-only product directly but may threaten the integrity of the underlying platform.

4. Additional Information:

Additional information may also be available via the Avaya support website and through your Avaya account representative. Please contact your Avaya product support representative, or dial 1-800-242-2121, with any questions.
