    SELinux prevented the CVS application from reading the shadow password file.
    The CVS application requires this access when it is configured for direct
    connection (i.e., pserver) and to authenticate to the system password / shadow
    files without PAM. It is possible that this access request signals an intrusion
    attempt.

    It is recommended that CVS be configured to use PAM, authenticate to a separate
    user file, or use another protocol (e.g., ssh) instead of allowing this access.
    See the CVS manual for more details on why this access is potentially insecure
    (<a href="http://ximbiot.com/cvs/manual/cvs-1.11.22/cvs_2.html">http://ximbiot.com/cvs/manual/cvs-1.11.22/cvs_2.html</a>).
