Hi,everybody!
I found some memory leaks in wget-1.12 source codes.The following lists
the bugs:

bug 1:
File:ftp-ls.c
Location: line 456
Description:
In function ftp_parse_winnt_ls, 
...
while ((line =read_whole_line(fp)) != NULL) {
        len = clean_line(line)
        if (len < 40)continue;  //Leak occured here, "line" is not released.
        ...
        ...
}

bug 2:
File : ftp.c
Location:       line 304
Description:
in function getftp(), 

getftp(...) {
...
...
    if (con->proxy) {
        logname = concat_strings(...);   //line 295, allocated a heap
region to logname
    }
...
csock = connect_to_host (host, port);
if (csock == E_HOST)
        return HOSTERR;      //return without free(logname)
...
...
}

I'm glad to get your replies if these are the real bugs .
