The problem can be corrected by upgrading the affected package to
version 5.1.1-2ubuntu3.1 (for Ubuntu 4.10), or 5.1.2-6ubuntu2.1 (for
Ubuntu 5.04). In general, a standard system upgrade is sufficient to
effect the necessary changes.
A remote Denial of Service has been discovered in the SMNP (Simple

the agent. Please note that by default SNMP uses UDP sockets.
