The OpenBSD team released an Errata entry 008_ip6rthdr for OpenBSD 4.2.

MFC (mcbride)
Correctly check that we have a complete rthdr before trying to do m_copydata()
on it.

I’ve made binpatches for i386, amd64 and sparc64.

The OpenBSD team released an Errata entry 007_tcprespond for OpenBSD 4.2.

Quote from the henning@’s commit message:

MFC (markus)
when creating a response, use the correct TCP header instead of
relying on the mbuf chain layout; with claudio@ and krw@; ok henning@

The OpenBSD team released an Errata entry 005_ifrtlabel for OpenBSD 4.2 in January.

I guess a binpatch is better late than never.

Quote from the henning@’s commit message:

MFC, initial fix by Chris Cappucino, more complete fix by me:
make sure users of rtlabel_id2name() can deal with no label present,
by not calling it when the label id is 0 (initial fix) and also checking
for rtlabel_id2name() returning NULL (complete fix). original rtlabel code
had that all right, the newer rtlabel bound to an interface code not.
impact: local users can cause a kernel panic by using the SIOCGIFRTLABEL
ioctl on interfaces with no route label assigned.
