"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."

"Several vulnerabilities have been discovered in NET SNMP, a suite of
Simple Network Management Protocol applications. The Common
Vulnerabilities and Exposures project identifies the following
problems :

  - CVE-2008-0960
    Wes Hardaker reported that the SNMPv3 HMAC verification
    relies on the client to specify the HMAC length, which
    allows spoofing of authenticated SNMPv3 packets.

  - CVE-2008-2292
    John Kortink reported a buffer overflow in the
    __snprint_value function in snmp_get causing a denial of
    service and potentially allowing the execution of
    arbitrary code via a large OCTETSTRING in an attribute
    value pair (AVP).

  - CVE-2008-4309
    It was reported that an integer overflow in the
    netsnmp_create_subtree_cache function in
    agent/snmp_agent.c allows remote attackers to cause a
    denial of service attack via a crafted SNMP GETBULK
    request."
