<font color="#009000"><strong>017: 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.

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.

A reference counting bug exists in the

An improper bounds check makes it possible for a local user to cause a crash
by passing the

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&amp;sektion=8">httpd(8)</a>

<font color="#009000"><strong>007: SECURITY FIX: October 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&amp;sektion=3">ssl(3)</a>.

Three cases of potential access to freed memory have been found in 
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pf&amp;sektion=4">pf(4)</a>.
At least one of them could be used to panic pf with active scrub rules remotely.<br>

<li><a name="sshbuffer"></a>
<font color="#009000"><strong>004: SECURITY FIX: September 16, 2003</strong></font><br>
All versions of OpenSSH's sshd prior to 3.7 contain a buffer management error.
It is unclear whether or not this bug is exploitable.<br>

An off-by-one error exists in the C library function
<a href="http://www.openbsd.org/cgi-bin/man.cgi?query=realpath&amp;sektion=3">realpath(3)</a>.
Since this same bug resulted in a root compromise in the wu-ftpd ftp server
it is possible that this bug may allow an attacker to gain escalated privileges
