<li><a name="tcp"></a>
<font color="#009000"><strong>013: RELIABILITY FIX: March 8,
2004</strong></font><br>
OpenBSD's TCP/IP stack did not impose limits on how many out-of-order
TCP segments are queued in the system. An attacker could
send out-of-order TCP segments and trick the system into using all
available memory buffers.

<p>
<li><a name="font"></a>
<font color="#009000"><strong>012: RELIABILITY FIX: February 14,
2004</strong></font><br>
Several buffer overflows exist in the code parsing
font.aliases files in XFree86. Thanks to ProPolice, these cannot be
exploited to gain privileges, but they can cause the X server to abort.
<br>
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/3.4/common/012_font.patch">
A source code patch exists which remedies the problem</a>.<br>
<p>
<li><a name="ip6"></a>
<font color="#009000"><strong>011: SECURITY FIX: February 8, 2004</strong></font><br>
An IPv6 MTU handling problem exists that could be used by an attacker
to cause a denial of service attack against hosts with reachable IPv6
TCP ports.
<br>
<a href="ftp://ftp.openbsd.org/pub/OpenBSD/patches/3.4/common/011_ip6.patch">

<p>
<li><a name="sysvshm"></a>
<font color="#009000"><strong>010: SECURITY FIX: February 5, 2004</strong></font><br>
A reference counting bug exists in the
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=shmat&apropos=0&sektion=2&manpath=OpenBSD+Current&format=html">shmat(2)</a>
system call that could be used by an attacker to write to kernel memory
under certain circumstances.

<p>
<li><a name="isakmpd"></a>
<font color="#009000"><strong>009: SECURITY FIX: January 13, 2004</strong></font><br>
Several message handling flaws in
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=isakmpd&apropos=0&sektion=8&manpath=OpenBSD+Current&arch=i386&format=html">isakmpd(8)</a>
have been reported by Thomas Walpuski. These allow an attacker to delete arbitrary SAs. The patch also
includes a reliability fix for a filedescriptor leak that causes problems when a crypto card is
installed.

<p>
<li><a name="sem"></a>
<font color="#009000"><strong>008: RELIABILITY FIX: November 20, 2003</strong></font><br>
An improper bounds check makes it possible for a local user to cause a crash
by passing the
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=semctl&apropos=0&sektion=2&manpath=OpenBSD+Current&arch=i386&format=html">semctl(2)</a> and

certain arguments.

<p>
<li><a name="uvm"></a>
<font color="#009000"><strong>007: RELIABILITY FIX: November 20, 2003</strong></font><br>
It is possible for a local user to cause a crash via
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sysctl&apropos=0&sektion=3&manpath=OpenBSD+Current&arch=i386&format=html">sysctl(3)</a> with certain arguments.

<p>
<li><a name="exec"></a>
<font color="#009000"><strong>005: RELIABILITY FIX: November 4, 2003</strong></font><br>
It is possible for a local user to cause a system panic by executing a specially crafted binary with an invalid header.

<p>
<li><a name="httpd"></a>
<font color="#009000"><strong>004: RELIABILITY FIX: November 1, 2003</strong></font><br>
A user with write permission to <tt>httpd.conf</tt> or a <tt>.htaccess</tt>
file can crash
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=httpd&sektion=8">httpd(8)</a>
or potentially run arbitrary code as the user <tt>www</tt> (although it
is believed that ProPolice will prevent code execution).

<p>
<li><a name="arp"></a>
<font color="#009000"><strong>003: RELIABILITY FIX: November 1, 2003</strong></font><br>
It is possible for a local user to cause a system panic by flooding it with spoofed ARP
requests.<br>

A source code patch exists which remedies the problem</a>.<br>
<p>
<li><a name="asn1"></a>
<font color="#009000"><strong>002: SECURITY FIX: November 1, 2003</strong></font><br>
The use of certain ASN.1 encodings or malformed public keys may allow an
attacker to mount a denial of service attack against applications linked with
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ssl&sektion=3">ssl(3)</a>.
This does not affect OpenSSH.<br>

<p>
<li><a name="cd_booklet"></a>
<font color="#009000"><strong>001: DOCUMENTATION FIX: November 1, 2003</strong></font><br>
The CD insert documentation has an incorrect example for package installation.<br>
Where it is written:<p>
<strong>
# pkg_add ftp://ftp.openbsd.org/pub/OpenBSD/3.4/packages/i386</strong><p>
It should instead read:<p>
<strong>
# pkg_add ftp://ftp.openbsd.org/pub/OpenBSD/3.4/packages/i386/</strong><p>
The extra <strong>/</strong> at the end is important. We do not make
patch files available for things printed on paper.

<ul>
<li><a name="ibcs2"></a>
<font color="#009000"><strong>006: SECURITY FIX: November 17, 2003</strong></font><br>
It may be possible for a local user to overrun the stack in
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=compat_ibcs2&sektion=8&apropos=0&manpath=OpenBSD+Current&arch=i386">compat_ibcs2(8)</a>.<br>
ProPolice catches this, turning a potential privilege escalation into a denial
of service. iBCS2 emulation does not need to be enabled via
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=sysctl&sektion=8&apropos=0&manpath=OpenBSD+Current&arch=i386">sysctl(8)</a>
for this to happen.
