The Simple Network Management Protocol (SNMP) is a protocol used for network management.
A denial-of-service flaw was found in the way Net-SNMP processes SNMP GETBULK requests. A remote attacker who issued a specially-crafted request could cause the snmpd server to crash. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2008-4309 to this issue.
Note: An attacker must have read access to the SNMP server in order to exploit this flaw. In the default configuration, the community name "public" grants read-only access. In production deployments, it is recommended to change this default community name.

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.
