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

129: When DMA'able memory is mapped by device drivers, the
130: mapping flags and protection are partially uninitialized.
131: Depending on the calling context, this may cause devices to misbehave, like

142: When pf attempts to perform translation on a specially crafted IP datagram,
143: a null pointer dereference will occur, resulting in a kernel panic.
144: In certain configurations this may be triggered by a remote attacker.
1.5 sthen 145: <br>
1.4 sthen 146: Restricting translation rules to protocols that are specific to the IP version
147: in use, is an effective workaround until the patch can be installed. As an
148: example, for IPv4 nat/binat/rdr rules you can use:
149: <pre>
150: nat/rdr ... inet proto { tcp udp icmp } ...
