Detail

Problem Description:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64 Red Hat Linux Advanced Workstation 2.1 - ia64 Red Hat Enterprise Linux ES version 2.1 - i386 Red Hat Enterprise Linux WS version 2.1 - i386

3. Description:

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.

4. Solution:

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188

5. Bugs fixed (http://bugzilla.redhat.com/):

447974 - CVE-2008-0960 net-snmp SNMPv3 authentication bypass (VU#877044)
