DESCRIPTION
ucd-snmp is an implementation and a set of tools to deal with the
Simple Network Management Protocol (SNMP), which is used for remote
administration and monitoring of network devices and services.

Axioma Security Research found[1] a remote heap overflow
vulnerability[2] in snmpnetstat (a tool used to retrieve information
about a remote host). When a list of interfaces is requested, a
malicious server can return information in a way that will cause a
heap overflow in snmpnetstat.

A remote atacker able to control a snmp server can exploit this
vulnerability to execute arbitrary code with the privileges of the
user running snmpnetstat.

SOLUTION
All ucd-snmp users should upgrade.
