III. Impact...
An attacker able to send LCP packets, including the remote end of a ppp(4)

ppp(4) or sppp(4)? Looking at the patch, it seems to be sppp(4), which is (completely?) seperate from ppp(4), AFAIK.
Also, ppp(8), Brian Somers userland PPP implementation, is not affected; a useful bit of information for people who are not as familiar with the multitude of PPP implementations in FreeBSD.
