"A vulnerability has been discovered and corrected in net-snmp :

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
(CVE-2012-2141).

The updated packages have been patched to correct this issue."
