The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.
A flaw was found in the way BIND handled trust anchor management. A remote attacker could use this flaw to cause the BIND daemon (named) to crash under certain conditions. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-1349 to this issue.

Recommended Actions for System 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.
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:
| Vulnerability | Mitigating Factors |
|---|---|
|
CVE-2015-1349 |
The risk is rated Low for CE because bind is not configured or running by default. The risk is rated Low for SM because bind is not accessible remotely and DNSSec is not used for validation. The risk is rated None for all other listed products because bind is not installed by default. Only bind-libs and bind-utils are installed for dependency purposes. |
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 Linux platform may be. Customers should determine on which Linux operating system the product was installed and then follow that vendor's guidance.
| Product: | Actions: |
|---|---|
| Avaya Aura® Experience Portal | Depending on the Operating System installed, the affected package may be installed on the underlying Operating System supporting the EP application. |
Recommended Actions for Software-Only Products:
In the event that the affected package is installed, Avaya recommends following recommended actions supplied by Red Hat regarding their Enterprise Linux.
