3. Description:

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

A flaw was found in the way Net-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)

A buffer overflow was found in the Perl bindings for Net-SNMP. This could
be exploited if an attacker could convince an application using the
Net-SNMP Perl module to connect to a malicious SNMP agent. (CVE-2008-2292)

All users of net-snmp should upgrade to these updated packages, which
contain backported patches to resolve these issues.

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/):

447262 - CVE-2008-2292 net-snmp: buffer overflow in perl module's Perl Module __snprint_value()
447974 - CVE-2008-0960 net-snmp SNMPv3 authentication bypass (VU#877044)
