CVE-2004-0564

Roaring Penguin pppoe (rp-ppoe), if installed or configured to run setuid
root contrary to its design, allows local users to overwrite arbitrary
files. NOTE: the developer has publicly disputed the claim that this is a
vulnerability because pppoe “is NOT designed to run setuid-root.”
Therefore this identifier applies only to those configurations and
installations under which pppoe is run setuid root despite the developer’s
warnings.
