I'm on a shared Linux host and have been wondering about security and directory "other" ["world"] permissions.

The defaults are 755. The 'others' [world] can read them only.

Is there a security hole if a dir on the doc root if a directory has permissions 757?

If there is a security problem, what is it?

Thanks...


If you have a directory with 757 permissions, "world" can create new
files there.

And if you give files 757 (or 646) permissions, then "world" can edit that file.

So if you have a doc dir, you probably don't want extra files there.
It's not really a security problem, but if somebody notices it, he
might write files there.
