12.3.6:
2 * added yuleadmin.pl script contributed by Riccardo Murri
3 * fix compile error with -f-stack-protector on some systems (reported
4 by marc); we now check for libssp
5 * fix local DoS attack on BSD systems lacking getpeereid() (reported
6 by Rob Holland).

8 rejected passwords with exactly 14 chars (reported by Jerry Brown)

10 found in regular file check (problem reported by J. Crutchfield);
11 also add regression test to ascertain that files in baseline
12 database are not quarantined erroneously

14 to allow for arbitrary module-specific store/lookup in db
15 * replace 'visited', 'reported', 'allignore' with generic 'fflags' field
16 * sh_cat.c: reduce priority of MSG_TCP_RESET to avoid spamming if
17 port checking is used on same host as server (reported by kadafax)

19 widgets (problem discovered by D. Denton)
