Re: Postfix incorrect permissions on configurations. Request.

The scripts inside are -world- executable, is the main concern here.  Certainly this can be changed by the end user but 
seems like an insecure default.  I've seen discussions and CVE's assigned for past cases where log directories are 
world readable and vice versa, if this is not the correct place to send, please advise.

Postfix is setting the following permissions by default on Debian Squeeze. I'm seeing roughly the same on 
RHEL/CentOS 6.x, this appears to be a requirement of "sendmail.postfix" 

0755 /etc/postfix
0644 /etc/postfix/*
0755 /etc/postfix-script
0755 /etc/post-install

Which allows all users to execute these scripts and read configurations. Setting to tighter/more typical 
permissions (i.e 640) results in: postfix/sendmail[21007]: fatal: open /etc/postfix/main.cf: Permission denied

That's all nice, but can you elaborate a bit -- what is wrong
with that? Which request do you have? What it has to do with
oss-security?

Thanks,
