Details

Updated ucd-snmp packages that fix a security issue are now available for
Red Hat Enterprise Linux 2.1.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

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.
