Description Konrad Karczewski 2006-08-05 17:12:27 UTC
After ppp installation the pppd has 4511 privileges and belongs to 'root:root'. It would be better to have execution permission limited to the group members by default - there's a 'dialout' group which probably can be used for this purpose. It's not a problem to this by hand but every update will of course 'reset' all changes and this creates a potential security risk.

pppd is used also for PPPoE, PPPoA and PPTP connections, not just for dial-up.
These permissions have been used by all distros since the beggining of time (pppd security track record is fairly clean).

Well the security track is fairly clean but not entirely spotless. As to the permissions: on Debian they're 4754 and ownership 'root:dip', and in RH 755 - there's no suid.
I don't want to say it's an extremely serious vulnerability but the proposed solution in not very complicated as well. Maybe the hardened team should be involved in this discussion?
