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

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

SNMP (Simple Network Management Protocol) is a protocol used for
network management.

A denial of service bug was found in the way ucd-snmp uses network
stream protocols. A remote attacker could send a ucd-snmp agent a
specially crafted packet which will cause the agent to crash. The
Common Vulnerabilities and Exposures project assigned the name
CVE-2005-2177 to this issue.

All users of ucd-snmp should upgrade to these updated packages, which
contain a backported patch to resolve this issue."
