Description Noah Petherbridge 2011-06-25 16:42:04 UTC
Description of problem:

One of Fedora 15's features was to start moving away from having the suid permission on executables and use a more secure system instead. However, this breaks mod_suexec in httpd because it needs the suid permission on /usr/sbin/suexec. The default permissions (0510) on this application don't work, and so mod_suexec doesn't work on the server.

Version-Release number of selected component (if applicable):

httpd-2.2.17-10.fc15.1.i686

How reproducible:

Always

Steps to Reproduce:
1. Install httpd, enable suexec by loading the module and adding SuexecUserGroup to a VirtualHost.
2. Make a test Perl script that simply prints the output of `id`
3. Test it. `id` will say the apache user is running.
4. chmod 4510 /usr/sbin/suexec and test again. `id` will say the user who owns the file is running.
  
Actual results:

Unless you add the setuid bit to suexec yourself, suexec doesn't work and the apache user runs your CGI scripts.

Expected results:

suexec should work without changing permissions.
