Patches for the OpenBSD base system are distributed as unified diffs.
Each patch contains usage instructions.
All the following patches are also available in one
tar.gz file
for convenience.
Patches for supported releases are also incorporated into the
-stable branch.

001: SECURITY FIX: April 27, 2007
  All architectures
 Incorrect mbuf handling for ICMP6 packets.
 Using
pf(4)
to avoid the problem packets is an effective workaround until the patch
can be installed.
 Use "block in inet6" in /etc/pf.conf

015: SECURITY FIX: March 30, 2008
  All architectures
 sshd(8) would execute ~/.ssh/rc even when a sshd_config(5) ForceCommand
directive was in effect, allowing users with write access to this file to
execute arbitrary commands. This behaviour was documented, but was an unsafe
default and an extra hassle for administrators.

016: SECURITY FIX: April 3, 2008
  All architectures
 Avoid possible hijacking of X11-forwarded connections with sshd(8)
by refusing to listen on a port unless all address families bind
successfully.
