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. Datagram TLS (DTLS) is a protocol based on TLS that is capable of securing datagram transport (for example, UDP).
Multiple denial of service flaws were discovered in OpenSSL's DTLS implementation. A remote attacker could use these flaws to cause a DTLS server to use excessive amounts of memory, or crash on an invalid memory access or NULL pointer dereference. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CVE-2009-1377, CVE-2009-1378, CVE-2009-1379, CVE-2009-1386 and CVE-2009-1387 to these issues.
Note: These flaws only affect applications that use DTLS. Red Hat does not ship any DTLS client or server applications in Red Hat Enterprise Linux.
An input validation flaw was found in the handling of the BMPString and UniversalString ASN1 string types in OpenSSL's ASN1_STRING_print_ex() function. An attacker could use this flaw to create a specially-crafted X.509 certificate that could cause applications using the affected function to crash when printing certificate contents. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2009-0590 to this issue.
Note: The affected function is rarely used. No application shipped with Red Hat Enterprise Linux calls this function, for example.
More information about these vulnerabilities can be found in the security advisory issued by RedHat Linux:
| Product: | Affected Version(s): | Risk Level: | Actions: |
|---|---|---|---|
| Avaya Voice Portal | 5.0 | Low | Upgrade to VP 5.1 or later. |
| Avaya Aura™ Session Manager | 1.1, 5.2 | Low | Upgrade to SM 6.0 or later. |
Recommended Actions:
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's
product and the surrounding network from this potential
vulnerability may be mitigated by ensuring these
practices are implemented until such time as a product
actions are applied. Further restrictions as deemed
necessary based on the customer's security policies
may be required during this interim period.
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: |
|---|---|
| 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. |
| Voice Portal | Depending on the Operating System provided by customers, the affected package may be installed on the underlying Operating System supporting the Voice Portal application. |
