Test ID:1.3.6.1.4.1.25623.1.0.870759
Category:Red Hat Local Security Checks
Title:RedHat Update for net-snmp RHSA-2012:0876-04
Summary:The remote host is missing an update for the 'net-snmp'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'net-snmp'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The net-snmp packages provide various libraries and tools for the Simple
Network Management Protocol (SNMP), including an SNMP library, an
extensible agent, tools for requesting or setting information from SNMP
agents, tools for generating and handling SNMP traps, a version of the
netstat command which uses SNMP, and a Tk/Perl Management Information Base
(MIB) browser.

An array index error, leading to an out-of-bounds buffer read flaw, was
found in the way the net-snmp agent looked up entries in the extension
table. A remote attacker with read privileges to a Management Information
Base (MIB) subtree handled by the 'extend' directive (in
'/etc/snmp/snmpd.conf') could use this flaw to crash snmpd via a crafted
SNMP GET request. (CVE-2012-2141)

These updated net-snmp packages also include numerous bug fixes. Space
precludes documenting all of these changes in this advisory. Users are
directed to the Red Hat Enterprise Linux 6.3 Technical Notes for
information on the most significant of these changes.

All users of net-snmp are advised to upgrade to these updated packages,
which contain backported patches to resolve these issues. After installing
the update, the snmpd and snmptrapd daemons will be restarted
automatically.

Affected Software/OS:
net-snmp on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
