Scientific Linux Security Update : net-snmp on SL6.x i386/x86_64

This script is Copyright (C) 2014 Tenable Network Security, Inc.

Synopsis :

The remote Scientific Linux host is missing one or more security

Description :

A buffer overflow flaw was found in the way the decode_icmp_msg()
function in the ICMP-MIB implementation processed Internet Control
Message Protocol (ICMP) message statistics reported in the
/proc/net/snmp file. A remote attacker could send a message for each
ICMP message type, which could potentially cause the snmpd service to
crash when processing the /proc/net/snmp file. (CVE-2014-2284)

This update also fixes the following bug :

- The snmpd service parses the /proc/diskstats file to
track disk usage statistics for
UCD-DISKIO-MIB::diskIOTable. On systems with a large
number of block devices, /proc/diskstats may be large in
size and parsing it can take a non-trivial amount of CPU
time. With this update, Net-SNMP introduces a new
option, 'diskio', in the /etc/snmp/snmpd.conf file,
which can be used to explicitly specify devices that
should be monitored. Only these whitelisted devices are
then reported in UCD-DISKIO- MIB::diskIOTable, thus
speeding up snmpd on systems with numerous block

After installing this update, the snmpd service will be restarted
