[Mediawiki-l] File Permissions

[Caplan, Hillel (US - New York)]

This comment is from

_should_I_do%3F:

"Here's another problem: It seems that a number of users are leaving the
/images directory set at 777 - globally writable. This permits malicious
users to take advantage of this and overwriting existing images with
their own spiteful images. It should be noted that this is not a
MediaWiki issue so much as it is a general permissions issue."

My question is: What is the recommended minimum permission setting?
