Comment 4 Jan Lieskovsky 2012-04-26 06:46:58 EDT
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.
