Bug 516450

The following was filed automatically by setroubleshoot:

Summary:

SELinux is preventing modem-manager (ModemManager_t) "read" device_t.

Detailed Description:

SELinux denied access requested by modem-manager. It is not expected that this
access is required by modem-manager 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://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report (http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this package.
