Symlink attacks

Two main symlink attacks:

Pointing to system files
     anurup$ cd ~
     anurup$ ls -l file
     lrwxrwxrwx 1 anurup anurup    11 Dec  0610:19 file -> /etc/shadow

Dangling symlinks
     anurup$ cd /tmp
     anurup$ ls -l file
     lrwxrwxrwx 1 anurup anurup    11 Dec  0610:19 file -> /root/.shosts

     anurup$ ls -l /root/.shosts
     ls: No such file or directory
