Updated net-snmp packages fix security vulnerabilities:

Remotely exploitable denial of service vulnerability in Net-SNMP,
in the Linux implementation of the ICMP-MIB, making the SNMP
agent vulnerable if it is making use of the ICMP-MIB table objects
(CVE-2014-2284).

Remotely exploitable denial of service vulnerability in Net-SNMP,
in snmptrapd, due to how it handles trap requests with an empty
community string when the perl handler is enabled (CVE-2014-2285).

A remote 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).
