worring about YaST in SuSE 9.3 and maybe lower

iam wondering about the installation routine from SuSE linux 9.3 and maybe some lower verisons.
YaST is creating a directory named "/var/adm/YaST/InstSrcManager/IS_CACHE_0x0000000X/DATA/descr" which is 
worldwritable by default. the directory contains data like packagenames and pathnames needed for YaST if you install 
software. for normal this directory shouldnt be writable by everyone because if you change the install media a new 
"IS_CACHE_0x0000000X/DATA/descr" is created which isnt worldwritable. 

so you may be able to poising the data which is viewd by root while he is trying to install data. the following data 
may be changed for example (file "packages"):

I cannot reproduce this directory being worldwriteable here.

What kind of installation source did you use? CD? ftp?

Ciao, Marcus
