Older versions of Apache httpd would blindly follow symlinks and overwrite files with its /tmp/apache_status file.

Subject: Bug in apache httpd 1.1.3
I noticed something interesting on my RedHat linux system (and on
some other linuxes).
httpd creates a file /tmp/apache_status, and follows blindly any
link if /tmp/apache_status points somewhere, for instance /etc/passwd. So
one can overwrite any file in the system. If she is able to create such a
link, and I don't think that's impossible.
The funny thing is that I have apache 1.1.3 installed on a SPARC
Solaris, and the problem doesn't exist there. So am I paranoid, or is
there a problem in the Apache server?
