Bug 545747

Summary:

SELinux is preventing /usr/bin/xauth access to a leaked unix_stream_socket file
descriptor.

Detailed Description:

[xauth has a permissive type (xauth_t). This access was not denied.]

SELinux denied access requested by the xauth command. It looks like this is
either a leaked descriptor or xauth output was redirected to a file it is not
allowed to access. Leaks usually can be ignored since SELinux is just closing
the leak and reporting the error. The application does not use the descriptor,
so it will run properly. If this is a redirection, you will not get output in
the unix_stream_socket. You should generate a bugzilla on selinux-policy, and it
will get routed to the appropriate package. You can safely ignore this avc.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385)
