klprfax_filter symlink vulnerability

[wang yuan <r0gue () 21cn com>]

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.

Cheers
