Description Richard P. Spillane 2011-01-19 22:48:30 UTC
SELinux is preventing /usr/libexec/polkit-1/polkit-agent-helper-1 from read, append access on the file /home_private/rick/.xsession-errors.

*****  Plugin catchall_labels (71.9 confidence) suggests  ********************

If you want to allow polkit-agent-helper-1 to have read append access on the .xsession-errors file
Then you need to change the label on /home_private/rick/.xsession-errors
Do
# semanage fcontext -a -t FILE_TYPE '/home_private/rick/.xsession-errors'
where FILE_TYPE is one of the following: policykit_auth_t, policykit_var_lib_t, policykit_var_run_t, user_cron_spool_t, faillog_t, policykit_reload_t, pcscd_var_run_t, policykit_tmp_t, root_t. 
Then execute: 
restorecon -v '/home_private/rick/.xsession-errors'


*****  Plugin leaks (14.7 confidence) suggests  ******************************

If you want to ignore polkit-agent-helper-1 trying to read append access the .xsession-errors file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# grep /usr/libexec/polkit-1/polkit-agent-helper-1 /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (14.7 confidence) suggests  ***************************

If you believe that polkit-agent-helper-1 should be allowed read append access on the .xsession-errors file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep polkit-agent-he /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
