Description Arivumani Durairaj 2011-05-10 05:55:19 UTC
SELinux is preventing /usr/sbin/semodule from 'write' accesses on the file /root/.xsession-errors.

*****  Plugin leaks (50.5 confidence) suggests  ******************************

If you want to ignore semodule trying to write 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/sbin/semodule /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (50.5 confidence) suggests  ***************************

If you believe that semodule should be allowed write 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 semodule /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Are you logging in as root via X?  

This is not allowed by SELinux.
