Summary:

SELinux is preventing /usr/bin/xauth "write" access on X0.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

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