Hello Kurt, Steve, vendors,

an array index error, leading to out-of heap-based buffer read
flaw was found in the way net-snmp agent performed entries lookup
in the extension table. When certain MIB subtree was handled by the
extend directive, a remote attacker having read privilege to the
subtree could use this flaw to cause a denial of service (snmpd
crash) via SNMP GET request involving a non-existent extension 
table entry.
