while add a invalid service in the directory of /etc/chkconfig.d, execute chkconfig will coredump

steps to reproduce:
1.add a service in /etc/chkconfig as below:

#!/bin/bash
# chkconfig: 8 33 99
echo "test chkconfig --override"

2. execute command ：chkconfig
   then os will produce coredump file.

the bug is produced from code below:

int readServiceInfo(char *name, int type, struct service *service,
                    int honorHide) {...
 asprintf(&filename, RUNLEVELS "/chkconfig.d/%s", name);
    if ((fd = open(filename, O_RDONLY)) >= 0) {
        parseret = parseServiceInfo(fd, name, &serv_overrides, honorHide, 1);  //here
        if (parseret >= 0) {
            if (serv_overrides.name)
                serv.name = serv_overrides.name;
...

and when level >6 , it will return 1 while the service name is random inited.
if (serv.levels == -1) { if (!strcmp(levelbuf, "-")) serv.levels = 0; else serv.levels = parseLevels(levelbuf, 0); } if (serv.levels == -1) { if (serv.desc) free(serv.desc); free(bufstart); return 1; }
