"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)"
