Debian security update to rp-pppoe

Posted Oct 5, 2004 0:19 UTC (Tue) by dskoll (subscriber, #1630) [Link]

This is only a Debian bug. pppoe is not designed to be suid or sgid. Although Debian fixes one problem, I would certainly not trust a suid or sgid pppoe executable.

Debian security update to rp-pppoe

Posted Oct 5, 2004 0:21 UTC (Tue) by dskoll (subscriber, #1630) [Link]

This is a Debian-specific bug. pppoe is not intended to be installed suid-root. Although the Debian maintainer has fixed one thing that makes it unsafe, there may be other things.
