net-snmp-5.7.2-24.el7

SNMP (Simple Network Management Protocol) is a protocol used for
network management. The NET-SNMP project includes various SNMP tools:
an extensible agent, an SNMP library, 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
mib browser. This package contains the snmpd and snmptrapd daemons,
documentation, etc.

You will probably also want to install the net-snmp-utils package,
which contains NET-SNMP utilities.

Security issues fixed with this release:

CVE-2014-3565
snmplib/mib.c in net-snmp 5.7.0 and earlier, when the -OQ option is
used, allows remote attackers to cause a denial of service (snmptrapd
crash) via a crafted SNMP trap message, which triggers a conversion to
the variable type designated in the MIB file, as demonstrated by a
NULL type in an ifMtu trap message.

Fixed bugs:

* Previously, the clientaddr option in the snmp.conf file affected outgoing messages sent only over IPv4. With this release, outgoing IPv6 messages are correctly sent from the interface specified by clientaddr.
* The Net-SNMP daemon, snmpd, did not properly clean memory when reloading its configuration file with multiple "exec" entries. Consequently, the daemon terminated unexpectedly. Now, the memory is properly cleaned, and snmpd no longer crashes on reload.
* Prior to this update, snmpd did not parse complete IPv4 traffic statistics, but reported the number of received or sent bytes in the IP-MIB::ipSystemStatsTable only for IPv6 packets and not for IPv4. This affected objects ipSystemStatsInOctets, ipSystemStatsOutOctets, ipSystemStatsInMcastOctets, and ipSystemStatsOutMcastOctets. Now, the statistics reported by snmpd are collected for IPv4 as well.
* The Net-SNMP daemon, snmpd, did not correctly detect the file system change from read-only to read-write. Consequently, after remounting the file system into the read-write mode, the daemon reported it to be still in the read-only mode. A patch has been applied, and snmpd now detects the mode changes as expected.
