Description

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.
