Description of problem:
I ran yum update.... 
SELinux is preventing /usr/sbin/xtables-multi from 'write' accesses on the file /tmp/ffiCAsWsp (deleted).

*****  Plugin leaks (86.2 confidence) suggests  ******************************

If you want to ignore xtables-multi trying to write access the ffiCAsWsp (deleted) 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.
# grep /usr/sbin/xtables-multi /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (14.7 confidence) suggests  ***************************

If you believe that xtables-multi should be allowed write access on the ffiCAsWsp (deleted) file 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 iptables /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
