  Seems like so. The fix [0] mainly replaces memcpys added by a former commit [1], which seems to be the main difference between the FreeBSD and Apple variant of ping [2], but probably that's not the source of the bug. What smells in there is 'hlen = ip->ip_hl << 2' [0] https://github.com/freebsd/freebsd-src/commit/46d7b45a267b3d78c5054b210ff7b6c55bfca42b https://github.com/freebsd/freebsd-src/commit/46d7b45a267b3d...
