OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library.
It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0169 to this issue.
A NULL pointer dereference flaw was found in the OCSP response verification in OpenSSL. A malicious OCSP server could use this flaw to crash applications performing OCSP verification by sending a specially-crafted response. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2013-0166 to this issue.
It was discovered that the TLS/SSL protocol could leak information about plain text when optional compression was used. An attacker able to control part of the plain text sent over an encrypted TLS/SSL connection could possibly use this flaw to recover other portions of the plain text. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2012-4929 to this issue.

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 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 customers should not modify the System Product
operating system or application 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-2012-4929 |
The risk is rated Low for all products because either compression is not used by default or part of the plain text is not under the control of remote attackers, making it difficult to extract any information from the encrypted connection. |
|
CVE-2013-0166 |
The risk is rated Low for all products because OCSP is not used by default. |
|
CVE-2013-0169 |
The risk is rated Low for CS1000 and Presence Services because they do not use openssl. The risk is rated Medium for all other products because of the possibility of an unauthorized user gaining sensitive information. |
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.
