概述:

SELinux is preventing the npviewer.bin from using potentially mislabeled files
(/root/.mozilla/firefox/4ctvyshh.default/.parentlock).

详细描述:

SELinux has denied npviewer.bin access to potentially mislabeled file(s)
(/root/.mozilla/firefox/4ctvyshh.default/.parentlock). This means that SELinux
will not allow npviewer.bin to use these files. It is common for users to edit
files in their home directory or tmp directories and then move (mv) them to
system directories. The problem is that the files end up with the wrong file
context which confined applications are not allowed to access.

允许访问:

If you want npviewer.bin to access this files, you need to relabel them using
restorecon -v '/root/.mozilla/firefox/4ctvyshh.default/.parentlock'. You might
want to relabel the entire directory using restorecon -R -v
'/root/.mozilla/firefox/4ctvyshh.default'.

audit2allow suggests:

#============= nsplugin_t ==============
allow nsplugin_t admin_home_t:file { write read };

Comment 1 Daniel Walsh 2009-09-16 12:37:33 UTC
You ran mozilla as root and it created this directory tree which nsplugin is now trying to interact with.  It is a horrible idea to run firefox as root.

rm -rf /root/.mozilla

Will eliminate this AVC.
