Good day!

I'm running Debian Lenny and I've noticed that
/usr/lib/cups/backend/{ipp,http,lpd} files are executable only by
root. Other installed backends do not have such restrictions:
$ ls -ls /usr/lib/cups/backend
total 244
 8 -rwxr-xr-x 1 root root  7200 2008-05-30 09:30 beh
12 -rwxr-xr-x 2 root root  8724 2008-04-02 03:46 dnssd
28 -rwx------ 3 root root 26104 2008-06-10 17:49 http

20 -rwxr-xr-x 2 root root 19312 2008-06-10 17:49 usb

I have two questions regarding this:
1. Why special restrictions are applied to ipp/lpd/http?
2. What are consequences of "chmod 755 /usr/lib/cups/backend/ipp"?

Thank you in advance.
