Description avignon 2011-08-23 11:02:22 UTC
SELinux is preventing /usr/sbin/tzdata-update from 'read' accesses on the directory /home/avignon.

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

If you believe that tzdata-update should be allowed read access on the avignon directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep tzdata-update /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

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

If you want to ignore tzdata-update trying to read access the avignon directory, 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.
# grep /usr/sbin/tzdata-update /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

Do you know when this happened? Were you updating system?

Comment 2 Daniel Walsh 2011-08-24 02:52:13 UTC
Were you doing a yum update while sitting in your homedir?

Comment 3 avignon 2011-08-24 05:55:50 UTC
Hi All,

I was actually performing an yum update from my home directory. is there a problem with doing so ?

(the upgrade was the one following a switch from testing to rawhide repositories, for a new computer)

Comment 4 Daniel Walsh 2011-08-26 21:29:19 UTC
No, it just that some apps have a nasty habit of searching their current directory when they start,  If they are confined, you will see an AVC message like this, the app will work fine, and you can ignore this avc.

If you don't want to see these just cd /; yum -y update

And you should be fine.
