[Artemii Voronin]

There is a possible memory leak. We allocated memory in the line №1205 inside function netsnmp_table_row_add_inde and it leaked in the line №1197.

net-snmp/agent/helpers/table_dataset.c

Lines 1193 to 1206 in 3a8e8ff

 for (vb = tables->table_set->table->indexes_template; vb; 
      vb = vb->next_variable) { 
     if (!line) { 
         config_pwarn("missing an index value"); 
         SNMP_FREE (row); 
         return; 
     } 
  
     DEBUGMSGTL(("table_set_add_row", "adding index of type %d\n", 
                 vb->type)); 
     buf_size = sizeof(buf); 
     line = read_config_read_memory(vb->type, line, buf, &buf_size); 
     netsnmp_table_row_add_index(row, vb->type, buf, buf_size);
