<h3>Changes made between OpenBSD 3.5 and 3.6</h3>
<p>

<ul>
<li>Fix <a href="https://man.openbsd.org/tcpdump.8">tcpdump(8)</a>'s <a href="https://man.openbsd.org/bpf.4">bpf(4)</a> attachment on <a href="https://man.openbsd.org/atw.4">atw(4)</a> devices.
<!-- ^ 20040912 -->
<li><strong>SECURITY FIX: Eilko Bos reported that radius authentication, as implemented by login_radius(8), was not checking the shared secret used for replies sent by the radius server.</strong> This could allow an attacker to spoof a reply granting access to the attacker. Note that OpenBSD does not ship with radius authentication enabled.<br>
    <a href="errata36.html#radius">A source code patch is available</a>.<br>
    <a href="stable.html">[Applied to stable]</a>
<!-- ^ 20040911 -->
<li>Bail out of <a href="https://man.openbsd.org/newfs.8">newfs(8)</a> on errors when making very small filesystems.
<!-- ^ 20040910 -->
<li>Move MIPS to 64-bit.
<li>Fix <a href="https://man.openbsd.org/copyout.9">copyout(9)</a> of <a href="https://man.openbsd.org/pf.4">pf(4)</a> anchors with relative paths and wildcards.
<li>Track the peer count correctly in <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a> and <a href="https://man.openbsd.org/ntpd.8">ntpd(8)</a>, fixing memory corruption in both.
<li>Fix a null dereference in <a href="https://man.openbsd.org/dhcpd.8">dhcpd(8)</a>.
<li>Just print the raw IP protocol number in <a href="https://man.openbsd.org/netstat.1">netstat(1)</a> instead of fetching the protocol name.
<!-- ^ 20040909 -->
<li>Stop <a href="https://man.openbsd.org/routed.8">routed(8)</a> fiddling with routes controlled by <a href="https://man.openbsd.org/bgpd.8">bgpd(8)</a>.
<li><strong>SECURITY FIX: <a href="https://man.openbsd.org/httpd.8">httpd(8)</a>'s mod_rewrite module can be made to write one zero byte in an arbitrary memory position outside of a char array,</strong> causing a DoS or possibly buffer overflows. This would require enabling dbm for mod_rewrite and making use of a malicious dbm file.<br>
    <a href="errata36.html#httpd2">A source code patch is available</a>.<br>
    <a href="stable.html">[Applied to stable]</a>
<li>Stop <a href="https://man.openbsd.org/telnetd.8">telnetd(8)</a> closing the slave fd from <a href="https://man.openbsd.org/openpty.3">openpty(3)</a> and then reopening it.
<!-- ^ 20040908 -->
<li>Set a cleanup handler for HUP as well as INT, TERM and WINCH on the <a href="https://man.openbsd.org/ssh.1">ssh(1)</a> multiplex control socket.
<li>Stop <a href="https://man.openbsd.org/ntpd.8">ntpd(8)</a> dying on <a href="https://man.openbsd.org/sendmsg.2">sendmsg(2)</a> failures.
<li>Unbreak <a href="https://man.openbsd.org/route.8">route(8)</a>'s -netmask option.
<li>Fix a bad cast from mode_t to short in <a href="https://man.openbsd.org/ar.1">ar(1)</a>.
<!-- ^ 20040907 -->
<li>Check for interrupted waits in <a href="https://man.openbsd.org/inetd.8">inetd(8)</a>, fixing late reaping of zombie processes and other ignored signals.
<!-- ^ 20040906 -->
<!-- ^ 20040905 -->
<!-- ^ 20040904 -->
<li>Don't busy-wait on ENOBUFS in <a href="https://man.openbsd.org/pppoe.8">pppoe(8)</a>.
<!-- ^ 20040903 -->
<li>Stop the mixer resetting <a href="https://man.openbsd.org/emu.4">emu(4)</a>'s volume to very very loud.
<!-- ^ 20040902 -->
<li>Make sure kernfs_xread() isn't called with a negative offset.
<li><strong>SECURITY FIX: Chris Evans reported several flaws (stack and integer overflows) in the Xpm library code that parses image files (CAN-2004-0687, CAN-2004-0688).</strong> Some of these would be exploitable when parsing malicious image files in an application that handles XPM images, if they could escape ProPolice.<br>
    <a href="errata36.html#xpm">A source code patch is available</a>.<br>
    <a href="stable.html">[Applied to stable]</a>
<!-- ^ 20040901 -->
<li>Stop non-MASTER <a href="https://man.openbsd.org/carp.4">carp(4)</a> hosts replying to ARP requests, as this upsets some layer 3 switches.
<!-- ^ 20040831 -->
<li>Stop <a href="https://man.openbsd.org/login.1">login(1)</a> treating the 'bar' in username foo.bar as a Kerberos instance, that's a krb4 syntax we no longer use.
<li>Fix fd passing problems with S/Key on sparc*.
<li>Don't do DNS lookups when reading <a href="https://man.openbsd.org/ntpd.8">ntpd(8)</a>'s config, save them for later.
<li>In <a href="https://man.openbsd.org/ntpd.8">ntpd(8)</a>, don't log transient network errors from <a href="https://man.openbsd.org/sendto.2">sendto(2)</a>.
<li>Fix <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a>'s handling of adaptive timeouts.
<li>Enforce minimum lease time of 60 seconds in <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>, to stop bogus 0s leases from the server causing the client to spin.
<li>Fix oversized copies that were causing memory faults in <a href="https://man.openbsd.org/usb.4">usb(4)</a>.
<!-- ^ 20040830 -->
<!-- ^ 20040829 -->
<li>Don't close stdin in <a href="https://man.openbsd.org/sshd.8">sshd(8)</a> unless we're reexec'ing.
<!-- ^ 20040828 -->
<li>Make sure <a href="https://man.openbsd.org/pkg_create.1">pkg_create(1)</a> keeps track of the current working directory.
<!-- ^ 20040827 -->
<li><strong>RELIABILITY FIX: Due to incorrect error handling in zlib an attacker could potentially cause a denial of service attack (CAN-2004-0797).</strong><br>
    <a href="errata36.html#libz">A source code patch is available</a>.<br>
    <a href="stable.html">[Applied to stable]</a>
<!-- ^ 20040826 -->
<li>Have /etc/<a href="https://man.openbsd.org/security.8">security(8)</a> store a copy of the disklabel and report any changes.
<!-- ^ 20040825 -->

<li>Don't make <a href="https://man.openbsd.org/ntpd.8">ntpd(8)</a> explode when <a href="https://man.openbsd.org/getaddrinfo.3">getaddrinfo(3)</a> returns EAI_NONAME.
<li>Base the value of uvm_km_pages_lowat on the amount of physical memory.

<li>Merge in Perl 5.8.3 and <!-- 20040408 --> OpenSSL 0.9.7d. No lame new licenses for a change.
<li>Now that <a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a> needs an instance per interface, having a single lease file won't do so use /var/db/dhclient.leases.&lt;ifname&gt;.
<li>Make sure the list dereference when deleting all SAs in <a href="https://man.openbsd.org/isakmpd.8">isakmpd(8)</a> comes before the delete operation that <a href="https://man.openbsd.org/free.3">free(3)</a>s the list node.

<!-- ^ 20040407 -->
<li>Make <a href="https://man.openbsd.org/newsyslog.8">newsyslog(8)</a>'s file renaming and copying operations set the same permissions in all cases.

<li>3.5 -&gt; 3.5-current.
<li>Change <a href="https://man.openbsd.org/wskbd.4">wskbd(4)</a>'s AltGr key handling so shift-altgr-other has the same effect as altgr-shift-other.
<li>Never allow <a href="https://man.openbsd.org/pf.4">pf(4)</a> states propogated via <a href="https://man.openbsd.org/pfsync.4">pfsync(4)</a> to overwrite newer states held locally. If an overwrite is attempted, broadcast the newer version to the network to speed resynchronisation.
