Dear all,

after being unable to update to latest since end of December and updating successfully, I see the following alerts.  I try to submit reports but abrt? is crashing :(  

Thanks for any pointers/advice/suggestions in advance,

Regards,


Antonio 


Summary:

SELinux is preventing /usr/sbin/abrtd (deleted) "write" access on /etc/abrt.

Detailed Description:

[abrtd has a permissive type (abrt_t). This access was not denied.]

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

Summary:

SELinux is preventing /usr/sbin/cupsd "read" access to
/etc/cups/ppd/Cups-PDF.ppd.

Detailed Description:

SELinux denied access requested by cupsd. /etc/cups/ppd/Cups-PDF.ppd may be a
mislabeled. /etc/cups/ppd/Cups-PDF.ppd default SELinux type is cupsd_rw_etc_t,
but its current type is tmp_t. Changing this file back to the default type, may
fix your problem.

File contexts can be assigned to a file in the following ways.

  * Files created in a directory receive the file context of the parent
    directory by default.
  * The SELinux policy might override the default label inherited from the
    parent directory by specifying a process running in context A which creates
    a file in a directory labeled B will instead create the file with label C.
    An example of this would be the dhcp client running with the dhclient_t type
    and creating a file in the directory /etc. This file would normally receive
    the etc_t type due to parental inheritance but instead the file is labeled
    with the net_conf_t type because the SELinux policy specifies this.
  * Users can change the file context on a file using tools such as chcon, or
    restorecon.

This file could have been mislabeled either by user error, or if an normally
confined application was run under the wrong domain.

However, this might also indicate a bug in SELinux because the file should not
have been labeled with this type.

If you believe this is a bug, please file a bug report against this package.

Allowing Access:

You can restore the default system context to this file by executing the
restorecon command. restorecon '/etc/cups/ppd/Cups-PDF.ppd', if this file is a
directory, you can recursively restore using restorecon -R
'/etc/cups/ppd/Cups-PDF.ppd'.

Fix Command:

/sbin/restorecon '/etc/cups/ppd/Cups-PDF.ppd'
