Description Nicolas Mailhot 2011-07-09 12:12:07 UTC
SELinux is preventing /sbin/ldconfig from 'read' accesses on the dossier /root.

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

If you want to ignore ldconfig trying to read access the root 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.
Do
# grep /sbin/ldconfig /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

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

If you believe that ldconfig should be allowed read access on the root directory 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 ldconfig /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Were you sitting in /root when you did the "yum update"?

Comment 2 Daniel Walsh 2011-07-11 22:09:27 UTC
Added dontaudit in rawhide

No idea, sorry, lately my system does not resist to rawhide updates long enough to investigate properly. Thank you for the fix
