/ is word writable ( Just wonder why??? )

[Gilberto Ferreira]

Hello friends...

I start this post wishing Happy New Year for everybody...

Now, the problem!

Today, I get this error on Zentyal 4:

Error output: ERROR: / is world writable!

So, as a result, none of service running properly... Squid, samba, ssh and others services just stuck...

I make some search on google and found out that the problem is a wrong write permissions on "/"

Indeed, when I check "/" filesystem with ls -ld / command, I figure out the is as follow:

drwsrwsrwx 22 root root 4096 Jan  2 11:15 /

I do not have any glue why this happen... I apply last updates from Zentyal apt servers and Ubuntu servers...

Somebody here have the very same problem???

Of course, I was able to fix the problem, fixing the right permission to "/"...

But I do not know the cause of the problem...

Anybody else??

Thanks a lot
