SEAlert:
=================================================
Summary
SELinux is preventing /usr/sbin/httpd (httpd_t) "execstack" to <Unknown>
(httpd_t).
Detailed Description
SELinux denied access requested by /usr/sbin/httpd. It is not expected that
this access is required by /usr/sbin/httpd and this access may signal an
intrusion attempt. It is also possible that the specific version or
configuration of the application is causing it to require additional access.
Allowing Access
You can generate a local policy module to allow this access - see
http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable
SELinux protection altogether. Disabling SELinux protection is not
recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
against this package.
