! 91: On very high system load, an audio interrupt may occur while the
! 92: audio process is filling audio ring buffers. This triggers bogus
! 93: (and useless) correction code in the
! 94: <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=audio&sektion=4">audio(4)</a>
! 95: driver causing the audio application to go out of sync, and in turn causing
! 96: continuous stuttering until the application is restarted.

! 116: When DMA'able memory is mapped by device drivers, the

129: When pf attempts to perform translation on a specially crafted IP datagram,
130: a null pointer dereference will occur, resulting in a kernel panic.
131: In certain configurations this may be triggered by a remote attacker.
1.5 sthen 132: <br>
1.4 sthen 133: Restricting translation rules to protocols that are specific to the IP version
134: in use, is an effective workaround until the patch can be installed. As an
135: example, for IPv4 nat/binat/rdr rules you can use:
136: <pre>
137: nat/rdr ... inet proto { tcp udp icmp } ...
138: </pre>
139: Or for IPv6 nat/binat/rdr rules you can use:
