hi,all ! i'm sorry if this bug has been reported. klprfax_filter (kdeutils-2.2-2),is an application to make a printer that acts as a fax. when using klprfax_filter,it would creat a temp file,/tmp/klprfax.filter,but the temporary file was not created safely,this vulnerability could be exploited to overwrite arbitrary files! just tested on redhat 7.1.
