Description Dawid Zamirski 2013-04-03 02:00:24 UTC
Description of problem:
SELinux is preventing /usr/bin/bash from 'execute' accesses on the file ldconfig.

*****  Plugin catchall (100. confidence) suggests  ***************************

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

Comment 1 Daniel Walsh 2013-04-08 16:56:52 UTC
6623b717e7a1185d2c54b00420bbb139f1810ebc fixes this in git.  Just allow it although it is not really needed.  These are caused by random scripts in /etc/profile.d directory.

Comment 2 Miroslav Grepl 2013-04-09 08:56:48 UTC
back ported.
