ftp://ftp.freebsd.org/pub/FreeBSD/releases/ISO-IMAGES/9.2/
Changes between -RC3 and -RC4 include:
o Revert the tribute boot loader logo as the default logo.
o Fix a filesystem bug that would cause removed files to fail to
dereference vnodes until the filesystem was forcibly unmounted
and remounted.
o Fix a rtadvd(8) segmentation fault on service reload.
o Create and correct ownership and permissions of /var/authpf in the
standard mtree.
o Fix a NFS deadlock.
o Stop SIOCSIFADDR, SIOCSIFBRDADDR, SIOCSIFDSTADDR and
SIOCSIFNETMASK at the socket layer rather than pass them on to the
link layer without validation or credential checks. [SA-13:12]
o Prevent cross-mount hardlinks between different nullfs mounts of
the same underlying filesystem. [SA-13:13]
o Fix the length calculation for the final block of a sendfile(2)
transmission which could be tricked into rounding up to the
nearest page size, leaking up to a page of kernel memory.
