This update to net-snmp resolves the following issues :
Specially crafted SNMP GET requests could cause a denial of service (application crash) via a heap-based out-out-bounds read flaw which could be exploited remotely. (CVE-2012-2141)
The snmpd agent should read shared memory information from /proc/meminfo when running on Linux Kernel 2.6 or newer. (bnc#762887)
The snmpd agent could crash when an AgentX sub-agent disconnects in the middle of a request. (bnc#670789)
After rotating the net-snmp log file, use ‘try-restart’ to restart the daemon. Reloading with a SIGHUP signal may trigger crashes when dynamic modules (dlmod) are in use. (bnc#762433)
