"Updated net-snmp packages that fix a security issue are now available
for Red Hat Enterprise Linux 3, 4, and 5.

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 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."
