We have not pppd at all, in any supported branch. We had pppd(8) and ppp(4) kernel driver used by pppd upto FreeBSD 7 and they did panic kernel if used with MPSAFE knob enabled, because ppp(4) was not mp-safe. Due to that reason (and nobody updated the driver), both of ppp(4) and pppd(8) were removed before 8.0-RELEASE. We have net/mpd5 daemon that can be used instead of pppd and mpd5 is not vulnerable due to its completely different code base including part parsing EAP messages. And, of course, we have ppp(8) "user-ppp" utility. _______________________________________________ freebsd-security@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-security To unsubscribe, send any mail to "freebsd-security-unsubscr...@freebsd.org"
