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
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4.tar.gz">tar.gz file</a>
for convenience.
<p>
Patches for supported releases are also incorporated into the
<a href="stable.html">-stable branch</a>.

<i>All architectures</i><br>
The readv(2) and writev(2) system calls would not accept a <em>struct iovec</em>

<p>
<li id="rst">

<i>All architectures</i><br>
A problem with NFS version 3 mounts on big endian machines (m68k, sparc
and powerpc) exists when mounting filesystems larger than 2gig. You
can see evidence of the bug by running df(1) and checking for negative
partition sizes.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/common/nfs3.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li id="termcap">
<font color="#009000"><strong>SECURITY FIX</strong></font>
<i>All architectures</i><br>
A security problem exists in the curses and ocurses libraries that affect
setuid programs linked with -lcurses or -locurses.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/common/termcap.patch">
A source code patch exists which remedies this problem.</a>
<br>
Precompiled versions of libcurses and libocurses exist for the
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/i386/curses.tar.gz">i386</a>
platform. Unpack it in /usr/lib.

restore the correct cursor position on exit.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/common/terminfo.src.patch">
A source code patch exists which remedies this problem.</a>
<br>
Alternately, you can also download a pre-compiled terminfo file to be
installed as <strong>/usr/share/misc/terminfo.db</strong>. For i386,
alpha and mips, use the
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/common/terminfo.db-LE.tar.gz">
little endian</a> version. For sparc, m68k and powerpc, use the
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/common/terminfo.db-BE.tar.gz">
big endian</a> version.
<p>
<li id="userdir">
<font color="#009000"><strong>FUNCTIONALITY FIX</strong></font>
<i>All architectures</i><br>
<strong>userdir</strong> support was accidentally left out of httpd(8).
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/common/userdir.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li id="bootpd">
<font color="#009000"><strong>SECURITY FIX</strong></font>
<i>All architectures</i><br>
A remotely exploitable problem exists in bootpd(8). bootpd is disabled
by default, but some people may actually be using it.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/common/bootpd.patch">
A source code patch exists which remedies this problem.</a>
This is the second version of the patch.
<p>
<li id="tcpfix">
<font color="#009000"><strong>SECURITY FIX</strong></font>
<i>All architectures</i><br>
A remote machine lockup problem exists in the TCP decoding code.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/common/tcpfix.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li id="tss">
<font color="#009000"><strong>SECURITY FIX</strong></font><br>
This is another fix for a kernel crash caused by the
<strong>crashme</strong> program.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/i386/tss.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li id="bootargv">
<font color="#009000"><strong>FUNCTIONALITY FIX</strong></font><br>
The kernel was using a fixed and hard-coded location for the arguments
vector passed from the <strong>/boot</strong> loader. This prevented
<strong>/boot</strong> from placing the boot arguments vector at any
other location, causing a kernel crash early in the autoconfiguration
stage. In 2.5, the bootblocks will be modified to use a new location.
Hence, if you wish old kernels to boot on a new bootblock, those
kernels will only work if they were linked with this patch.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/i386/bootargv.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li id="trctrap">
<font color="#009000"><strong>SECURITY FIX</strong></font><br>
i386 trace-trap handling when DDB was configured could cause a system
crash.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/i386/trctrap.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li id="installboot">
<font color="#009000"><strong>FUNCTIONALITY FIX</strong></font><br>
i386 installboot had a sign extension bug which prevented proper bootblock
initialization when the root filesystem was placed beyond 4GB.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/i386/installboot.patch">
A source code patch exists which remedies this problem.</a>
Unfortunately, updated 2.4 install floppies are not available. Just ensure
that your root filesystem is below 4GB, for now.
<p>
<li id="hme">
<font color="#009000"><strong>DRIVER FIX</strong></font><br>
The sparc hme(4) and be(4) drivers work poorly on some types of SS-20
machines. This is because those machines lie, saying they support 64-bit DMA
bursting. No sun4m machines support that.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/sparc/hme.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li id="le">
<font color="#009000"><strong>DRIVER FIX</strong></font><br>
The sparc le(4) driver does media changes incorrectly on one type of
sbus le(4) card.
<a href="https://ftp.openbsd.org/pub/OpenBSD/patches/2.4/sparc/le.patch">
A source code patch exists which remedies this problem.</a>
<p>
<li id="hp300X">
<font color="#009000"><strong>FUNCTIONALITY FIX</strong></font><br>
The Xhp as shipped does not have the execute permissions set. The fix is
'chmod 755 /usr/X11R6/bin/Xhp' if you have installed X.
