Bug 639172

Summary:

SELinux is preventing /usr/bin/sudo "signal" access .

Detailed Description:

SELinux denied access requested by sudo. It is not expected that this access is
required by sudo 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.
