The OpenBSD ports collection does contain a vulnerable version of xntp.
The following extract was taken from the GNATs bug report about this issue:
Here is an addition to the OpenBSD xntpd port that applies
NAKAMURA Kazushi's patch.
How to apply:
# Add the new file: /usr/ports/sysutils/xntpd/patches/patch-ntp_control.c
make uninstall && make clean && make && make install
reboot # necessary because tickadj is run before system securelevel is changed
The new file /usr/ports/sysutils/xntpd/patches/patch-ntp_control.c is
NAKAMURA Kazushi's patch -- nothing more. It comes directly from the
FreeBSD tree. It may not be OpenBSD's preferred way of doing things,
but it will close the hole until OpenBSD has it fixed.
