SELinux is preventing boinc_client from execute access on the file /bin/bash.

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

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