3. Description:

 

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.

 

A denial of service flaw was found in the way snmptrapd handled certain

SNMP traps when started with the "-OQ" option. If an attacker sent an SNMP

trap containing a variable with a NULL type where an integer variable type

was expected, it would cause snmptrapd to crash. (CVE-2014-3565)

 

This update also fixes the following 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. (BZ#1190679)

 

* 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. (BZ#1228893)

 

* 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. (BZ#1235697)

 

* 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. (BZ#1241897)

 

All net-snmp users are advised to upgrade to these updated packages, which

contain backported patches to correct these issues.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.
