Description Philip Rowlands 2001-04-11 22:07:18 UTC
/etc/profile contains the following lines:

for i in /etc/profile.d/*.sh ; do
        if [ -x $i ]; then
                . $i
        fi
done

The test should be for read (-r) rather than execute (-x), because
source'ing a file reads it.

While you're at it, could you also fix /etc/csh.cshrc to use "-r" for this
test?

That's not a bug, it's just an easy way to turn it off :)

Comment 2 Philip Rowlands 2001-04-18 02:00:57 UTC
I would respectfully suggest that there are other ways to turn it off without 
requiring this broken behaviour (e.g rename to *.sh.x).

It is a bug because it's no guard against the conditional action successfully 
reading the file (ditto for csh.cshrc). Being able to execve() a file is not 
the same as being able to open() it.

I'm not reporting this to be pedantic; I've seen RPMs packaged by people who 
thought that a script file which is sourced needs read permissions; no more.

Will be fixed in 2.4.11-1; thanks!
