The snmp_pdu_parse function in snmp_api.c in net-snmp 5.7.2 and earlier does not remove the varBind variable in a netsnmp_variable_list item when parsing of the SNMP PDU fails, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted packet.

snmplib/mib.c in net-snmp 5.7.0 and earlier, when the -OQ option is used, allows remote attackers to cause a denial of service (snmptrapd crash) via a crafted SNMP trap message, which triggers a conversion to the variable type designated in the MIB file, as demonstrated by a NULL type in an ifMtu trap message.
