Bug 611030

Summary:

SELinux is preventing /usr/libexec/zoneminder/cgi-bin/nph-zms "unix_read
unix_write" access .  Happens when trying to view video stream in zoneminder's web UI.

Detailed Description:

SELinux denied access requested by nph-zms. It is not expected that this access
is required by nph-zms 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 FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug
report.
