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 would accept ephemeral RSA keys when using non-export RSA cipher suites. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0204 to this issue.
An integer underflow flaw, leading to a buffer overflow, was found in the way OpenSSL decoded malformed Base64-encoded inputs. An attacker able to make an application using OpenSSL decode a specially crafted Base64-encoded input (such as a PEM file) could use this flaw to cause the application to crash. Note: this flaw is not exploitable via the TLS/SSL protocol because the data being transferred is not Base64-encoded. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0292 to this issue.
A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0293 to this issue.
Multiple flaws were found in the way OpenSSL parsed X.509 certificates. An attacker could use these flaws to modify an X.509 certificate to produce a certificate with a different fingerprint without invalidating its signature, and possibly bypass fingerprint-based blacklisting in applications. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2014-8275 to this issue.
An out-of-bounds write flaw was found in the way OpenSSL reused certain ASN.1 structures. A remote attacker could possibly use a specially crafted ASN.1 structure that, when parsed by an application, would cause that application to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0287 to this issue.
A NULL pointer dereference flaw was found in OpenSSL's X.509 certificate handling implementation. A specially crafted X.509 certificate could cause an application using OpenSSL to crash if the application attempted to convert the certificate to a certificate request. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0288 to this issue.
A NULL pointer dereference was found in the way OpenSSL handled certain PKCS#7 inputs. An attacker able to make an application using OpenSSL verify, decrypt, or parse a specially crafted PKCS#7 input could cause that application to crash. TLS/SSL clients and servers using OpenSSL were not affected by this flaw. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2015-0289 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:
|CVE-2014-8275||The risk is rated Low for all listed products because the fingerprint-based certificate-blacklist protection mechanism is not used by default.|
|CVE-2015-0204||The risk is rated Low for all listed products because weak keys are disabled by default.|
|CVE-2015-0287||This is a Low risk for all listed products because OpenSSL is used for parsing certificates and certificate parsing is not affected by this vulnerability.|
|CVE-2015-0288||This is a Low risk for all listed products because untrusted X.509 certificates are not used and they are not converted to certificate requests without non-standard direct user interaction.|
|CVE-2015-0289||This is a Low risk for all listed products as only SSL/TLS secure connections are used and PKCS#7 input is not used by default without non-standard direct user interaction.|
|CVE-2015-0292||This is a Low risk for all listed products as only SSL/TLS secure connections are used and Base64-encoded input from untrusted sources is not used by default without non-standard direct user interaction.|
|CVE-2015-0293||This is a Low risk for all listed products because SSLv2 and EXPORT-grade cipher suites are disabled by default.|
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.
