Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications.
A flaw was found in the way TLS False Start was implemented in NSS. An attacker could use this flaw to potentially return unencrypted information from the server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-1740 to this issue.
A race condition was found in the way NSS implemented session ticket handling as specified by RFC 5077. An attacker could use this flaw to crash an application using NSS or, in rare cases, execute arbitrary code with the privileges of the user running that application. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-1490 to this issue.
It was found that NSS accepted weak Diffie-Hellman Key exchange (DHKE) parameters. This could possibly lead to weak encryption being used in communication between the client and the server. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-1491 to this issue.
An out-of-bounds write flaw was found in NSPR. A remote attacker could potentially use this flaw to crash an application using NSPR or, possibly, execute arbitrary code with the privileges of the user running that application. This NSPR flaw was not exposed to web content in any shipped version of Firefox. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-1545 to this issue.
It was found that the implementation of Internationalizing Domain Names in Applications (IDNA) hostname matching in NSS did not follow the RFC 6125 recommendations. This could lead to certain invalid certificates with international characters to be accepted as valid. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-1492 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-2013-1740 CVE-2014-1490 CVE-2014-1491 CVE-2014-1492 CVE-2014-1545 |
These are a Low risk as either the packages are installed but not used, or the affected functionality is not used. |
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.
