$OpenBSD: SECURITY,v 1.4 1999/11/21 23:42:53 espie Exp $ ${WRKDIR}/receiver.c call to mktemp (wrapper function do_mktemp) does seem to be correct. The server makes extensive use of strlcpy/strlcat/snprintf. rsync upto 2.3.0 has a security hole. If rsync --version is less or equal to that, you should upgrade. rsync 2.3.1 has security holes in the rsyncd daemon when run with chroot=no. If you are using that feature, you should upgrade.
