I just ran into the same problem on EPEL-5. It appears that the path
for the nagios cgi scripts is wrong in
/etc/selinux/targeted/contexts/files/file_contexts:
# grep nagios /etc/selinux/targeted/contexts/files/file_contexts
/usr/lib(64)?/nagios/cgi/.+ -- system_u:object_r:nagios_cgi_exec_t:s0
[...]
This should be:
/usr/lib(64)?/nagios/cgi-bin/.+ --
--Wart
You can add this yourself for now. I will update the U2 selinux policy
to fix this.
semodule fcontext -a -t nagios_cgi_exec_t \
"/usr/lib(64)?/nagios/cgi-bin/.+"
