Summary

The Simple Network Management Protocol (SNMP) is a protocol used for network management.
A flaw was found in the way ucd-snmp checked an SNMPv3 packet's Keyed-Hash Message Authentication Code (HMAC). An attacker could use this flaw to spoof an authenticated SNMPv3 packet. (CVE-2008-0960)
All users of ucd-snmp should upgrade to these updated packages, which contain a backported patch to resolve this issue.
