>Description:

Recent screen (3.9.11) has a bug with handling locales. It uses
unitialized variables in there, which turns to be a problem when
screen is set non-suid.

Here's more detailed problem description, along with the patch:

http://www.dekaino.net/screen/screen-3.9.11.seteuid-patch

	
>How-To-Repeat:

Install screen from ports. Remove the suid bit on the binary.
Set the LANG env to sth (pl_PL.ISO_8859-2 in my case).
Execute screen. You will get:

seteuid: Operation not permitted

	
>Fix:

The patch in the link above fixes this and works fine for me.
