I keep having odd messages like this pop up in my audit log. Can anyone explain the message a little so I can figure out what is going on?

CODE
type=AVC msg=audit(1165342012.221:1735): avc:  denied  { read write } for  pid=8193 comm="sh" name="ZCUDVff2C4" dev=loop0 ino=23 scontext=root:system_r:httpd_sys_script_t tcontext=root:object_r:httpd_tmp_t tclass=file
