OpenSSL is a toolkit that implements Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength, general purpose, cryptography library.
The Google security team discovered a flaw in the way OpenSSL checked the verification of certificates. An attacker in control of a malicious server, or able to effect a "man in the middle" attack, could present a malformed SSL/TLS signature from a certificate chain to a vulnerable client and bypass validation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-5077 to this issue.

For all vulnerable system products, Avaya recommends that customers restrict local and network access to the server. This restriction should be enforced through the use of physical security, firewalls, ACLs, VPNs, and other generally-accepted networking practices until such time as an update becomes available and can be installed.
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.
|CVLAN||Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the CVLAN application.|
|Avaya Integrated Management Suite (IMS)||Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the IMS application.|
